Description

  The present invention relates to hair products.

  Conventionally, when changing the hair color with hair color (dyeing), it has been difficult to objectively determine whether the finished hair color looks good to you or what impression it gives to others. . In recent years, there is also a simulation method in which the hair color is variously changed by a computer, a color sample, or the like, but the satisfaction of the user is not always obtained due to the difficulty in determining the suitability of the hair color.

  As a conventional technique related to changing the hair color, for example, a method of finishing a hair color that matches the user's skin color by selecting a hair color that matches the skin color system and coloring it is disclosed. (See Patent Document 1). In addition, when two types of hair color are mixed and dyed, in order to fill the gap between the customer's (user) and hairdresser's finished hair color image, the hair color finish is presented in advance using image simulation. The method of doing is also disclosed (refer patent document 2). Patent Document 3 will be described later.

Japanese Patent Laid-Open No. 2005-304637 JP-A-2005-274828 JP 2005-339522 A

  However, even if the method described in Patent Document 1 or Patent Document 2 is used, the finished hair color may not match the user as expected before the change in hair color, and the hair color that the user is satisfied with It was generally difficult to finish.

  In view of such a problem, as a result of intensive studies by the present inventors, it is clear that the appearance (appearance) of the subject's skin color changes by changing the hair color of the subject (user). It became. For this reason, the actual appearance that is confirmed based on the comparison between the appearance that was predicted in advance based on the appearance of the skin color before the change in hair color and the appearance of the skin that has changed in appearance with the change in hair color. , Was newly found to be inconsistent. Then, the present invention makes it possible for a subject or a beautician to know in advance the change in the appearance of the skin color when the hair color is changed. The color change material can be selected.

  That is, according to the present invention, it is a hair product that includes a hair color changing material that changes the hair color, the original skin color display unit that represents the skin color of the subject, and the subject's skin color using the hair color changing material. There is provided a hair article characterized in that the change skin color display portion representing the appearance color of the skin when the hair color is changed is displayed so as to be comparable with each other.

  According to the present invention, the appearance of the skin that changes due to the visual effect caused by changing the hair color with the hair color changing material is visually compared by comparing the colors of the original skin color display portion and the changed skin color display portion. It is possible to grasp. Thereby, the subject person, the hairdresser, and the like who change the hair color can appropriately select the changed hair color in consideration of the change in the appearance of the skin color in advance.

It is a schematic diagram which shows the hair goods concerning 1st embodiment. It is a conceptual diagram which shows the hair supplies group which displayed the skin color appearance change information based on 2nd embodiment. It is a conceptual diagram of the image used for Experimental example 1 among the sensory evaluation experiment which asks a test subject to select what the skin color of both images looks the same. It is a graph which shows the correlation of the appearance information of skin color, and the variation | change_quantity information of hair color regarding a hue. It is a graph which shows the correlation of the appearance information of skin color, and the variation | change_quantity information of hair color regarding saturation. It is a graph which shows the correlation of the appearance information of skin color, and the variation | change_quantity information of hair color regarding the brightness.

  It has been clarified by the present inventors that the visual impression of the hair color affects not only whether it suits the person but also the appearance of the skin color. For this reason, the customer himself / herself changes the appearance color of the skin color (hereinafter, also referred to as “skin color impression”) due to the change of the hair color in a subject who changes the hair color, for example, a drug store or a cosmetics department. Hair products that can be judged objectively are considered useful. However, hair products that take into account changes in the skin color impression have not yet been developed, and the inventor has focused on this point to complete the present invention.

<First embodiment>
The outline | summary of the hair goods of 1st embodiment of this invention is demonstrated. FIG. 1 is a schematic diagram showing a hair article 10 according to the present embodiment. In the present embodiment, an example in which a hair dye such as a hair color is used as the hair article 10 is shown.

  The hair article 10 includes a hair color changing material (hair dye: not shown) that changes the hair color. The hair article 10 of the present embodiment includes an original skin color display unit 20 that represents the color of the subject's skin, and the appearance color of the skin when the subject's hair color is changed using the hair color changing material. A change skin color display unit 21 representing (skin color impression) is displayed so as to be comparable with each other.

  In this embodiment, the hair dye (not shown) accommodated in the tube-shaped packaging container 16 is illustrated as a hair color changing material.

  According to the present embodiment, when the subject's hair color is changed by the hair color changing material (hair dye), the original skin color display unit 20 and the changed skin color display unit 21 can be compared. For this reason, the change in the appearance of the skin color before and after the change in the hair color can be visually recognized. Moreover, according to the hair article 10 of this embodiment, when the subject desires to positively change the skin color impression of the face by utilizing the change of the hair color, the original skin color display unit 20 and By contrasting with the changed skin color display unit 21, a desired degree of impression change can be visually determined.

  Here, the hair color means the appearance color of the hair (head hair). For example, it means the appearance color of the subject's hair color, such as black hair, brown hair, gray hair mixed with white hair (hereinafter, gray) hair, white hair, and the like.

  Skin color refers to color-scientific colors (lightness, saturation, and hue) related to facial skin. The skin may be bare skin or skin after makeup. The appearance color of the skin means an appearance impression regarding the skin color of the face when the hair and the skin of the face are viewed together. The appearance color of the skin can be evaluated sensuously after visually observing the head including the hair. That is, the appearance color of the skin is the color in which the appearance of the skin color is changed by the visual effect due to the change of the subject's hair color, regardless of the color of the skin. Say.

  This visual effect will be described. As a result of the study by the present inventors, it became clear that the appearance of the skin color of the face changes depending on the hair color covering the head. For example, when the original hair color (original hair color) is changed to a certain hair color, even if the skin color is not changed, the appearance of the skin color changes whitish, or conversely changes to lightness, etc. May occur. Similarly, changes in hue and saturation may occur, such as the skin color appearing vividly pinkish or conversely yellowish. This is because the three attributes of color and the change in color have an “anabolic” or “contrast” relationship. Here, “assimilation” means that the color appears to change with a positive correlation with the change in the color attribute, and “contrast” means that the color changes with a negative correlation with the change in the color attribute. It means that it can be seen.

  The color of the original skin color display unit 20 represents the skin color (original skin color) of the face before the hair color change. Similarly, the changed skin color display unit 21 represents a skin color (changed skin color) that matches the appearance of the skin color when the face after the hair color change is viewed. In the hair article 10, the original skin color display unit 20 and the change skin color display unit 21 can be compared with each other when the hair color changing material itself or a container or package that contains the hair color changing material directly or indirectly. Or the original skin color display part 20 and the change skin color display part 21 are displayed on the articles | goods distribute | circulated with a hair color change material, such as the label attached to the hair supplies 10, and an instruction manual. The original skin color display unit 20 and the changed skin color display unit 21 may be partially or entirely overlapped with each other. The original skin color display unit 20 and the changed skin color display unit 21 may be displayed at the same time, or may be displayed at different timings. The display of the original skin color display unit 20 and the changed skin color display unit 21 on the hair article 10 includes not only the state in which they are printed but also the display output on a display device such as a liquid crystal display device or electronic paper. .

  Although the display position and display mode of the original skin color display unit 20 and the change skin color display unit 21 are not particularly limited, in the present embodiment illustrated in FIG. 1, the original skin color display unit 20 is provided on the surface of the packaging container 16 (tube) of the hair article 10. And the change skin color display unit 21 are printed adjacent to each other. In addition, the original skin color display unit 20 and the changed skin color display unit 21 may be displayed on the surface of a storage package (not shown) that houses the packaging container 16. And it is preferable that the original skin color display part 20 and the change skin color display part 21 are simultaneously displayed in the position which can be visually recognized like this embodiment, Specifically, it displays on the same surface or the adjacent surface of the packaging container 16. Has been.

  This embodiment will be described more specifically. In the hair product 10 of this embodiment, a hair dye for white hair dyeing that changes an original hair color (for example, gray: original hair color) into another hair color (for example, black: changed hair color) is a tube-shaped packaging container 16. It is a hair dye product filled in.

  On the outer surface of the packaging container 16, an original hair color display section 30 and a changed hair color display section 31 that indicate the hair colors before and after being dyed by the hair dye are displayed. The original hair color display unit 30 and the changed hair color display unit 31 are linked by a hair color change indicator unit 39 that indicates the direction of change in the hair color. A change in the appearance of the skin color when the hair color is changed is expressed as a color difference between the original skin color display unit 20 and the changed skin color display unit 21. Between the original skin color display unit 20 and the changed skin color display unit 21, an arrow (shown as a white arrow in FIG. 1) from before hair dyeing to after hair dyeing is provided as a change direction indicator unit 18.

  The original skin color display unit 20 and the changed skin color display unit 21 are displayed such that the eyes, nose, mouth, and the like can be determined to indicate the skin color of the human face. And the original skin color display part 20 and the change skin color display part 21 are face shapes. Face shape refers to a geometrical shape such as a circle or an ellipse, a figure that is modeled to the extent that it is recognized as a human face in relation to the hairstyle shape, or a photograph or figure that faithfully represents the human face. . The face shape may include a part other than the face such as a neck and a torso as long as it includes at least a part of the face. On the other hand, the original hair color display unit 30 and the changed hair color display unit 31 are displayed in an arbitrary shape such as a circular shape.

  In the hair article 10 of the present embodiment, the original hair color display unit 30 representing the hair color is displayed separately from the original skin color display unit 20, and the changed hair color display representing the changed hair color using the hair color changing material. The part 31 is displayed separately from the change skin color display part 21. Thereby, an illusion effect such as assimilation or contrast does not occur between the original hair color display unit 30 and the original skin color display unit 20, and between the changed hair color display unit 31 and the changed skin color display unit 21.

  The original skin color display unit 20 and the changed skin color display unit 21 are colored in chromatically different colors. These color differences occur when a user or model having the same skin color as the original skin color display unit 20 changes the hair color from the color of the original hair color display unit 30 to the color of the changed hair color display unit 31. It represents the tendency of the impression change of the skin color that occurs visually.

  When the skin of the face having the same color as the original skin color display unit 20 and the hair of the user or model having the same color as the original hair color display unit 30 is changed to the color of the changed hair color display unit 31, the appearance color of the skin At least one of the three attributes (lightness, saturation, and hue) in the image changes due to assimilation or contrast effects. The difference in chromatic color between the changed skin color display unit 21 and the original skin color display unit 20 represents the tendency of this change (increase or decrease in brightness, increase or decrease in saturation, shift in hue). As will be described later in detail in the examples, the change in the appearance of the skin color with respect to the change in hair color has an assimilation relationship (positive correlation) between hue and saturation, and on the contrary, the brightness has a comparison relationship (negative). It is clear from the study by the present inventors. Therefore, when the hair product 10 of the present embodiment that reduces the lightness from the gray original hair color to the black change hair color, the lightness in the skin color impression of the face is increased by the contrast effect (illusion effect). The brightness of the changed skin color display unit 21 is higher than the brightness of the original skin color display unit 20. This indicates that the brightness of the user's skin color appears to have increased due to the contrast effect when the user's hair color decreases from the color of the original hair color display unit 30 to the color of the changed hair color display unit 31. Yes. In other words, the change of the skin color impression that changes only sensuously without changing chromatically before and after the use of the hair color changing material is represented by the chromaticity of the original skin color display unit 20 and the changed skin color display unit 21. In this embodiment, the color difference is displayed on the hair article 10 as a color difference. Thereby, according to the hair article 10 of this embodiment, the skin color at the time of using this hair color change material by a user contrast-observing the color of the original skin color display part 20 and the color of the change skin color display part 21. The degree of impression change can be clearly understood.

  Although the brightness has been described above, the changed skin color display unit 21 of the present embodiment may be different from the original skin color display unit 20 in terms of saturation and hue. In that case, the tendency of the difference in saturation or hue between the original skin color display unit 20 and the changed skin color display unit 21 is the coloration between the original hair color display unit 30 and the changed hair color display unit 31 before and after the use of the hair color changing material. Consistent with the trend of degree or hue difference.

  The difference in hue, saturation, or lightness (for example, lightness) between the original skin color display unit 20 and the changed skin color display unit 21 is obtained from the subject's hair of the color represented in the original hair color display unit 30 in this embodiment. The degree of change in the hue, saturation, or lightness (for example, lightness) related to the appearance color of the subject's skin when the hair color is changed using the hair product (hair color changing material) 10 It corresponds. In other words, when the hair product 10 of this embodiment is applied to the hair and the hair color is changed, the degree of change in the appearance of the skin color due to the optical illusion effect is as follows: the original skin color display unit 20 and the changed skin color display unit 21 This is consistent with the color difference.

  Here, the hair color changing material means an article that changes a subject's hair color in one or more ways. As long as the hair color changing material can change the hair color, the hair color changing material may be one or plural. For example, hair dyes, hair dyes, depigmenting agents, and the like may be applied directly to the hair. In this case, it may be applied to the entire hair, or may be applied only to a part of the hair. The hair dye is a so-called quasi-drug, and examples thereof include permanent hair dyes such as hair colors for fashion dyeing and hair coloring for gray hair dyeing. Depigmenting agents such as hair bleaches that remove hair color pigments and change hair color, decoloring agents, and the like are also types of hair dyes. The hair dye is a so-called cosmetic, and examples thereof include semi-permanent hair dyes such as hair nail polish, color shampoo and color rinse, color sprays, color sticks and the like, and temporary hair dyes that can be temporarily dyed and washed away with shampoo. . Other hair color changing materials include wigs to be worn on the entire head (all wigs), semi-wigs to be worn on a part of the head, and hair-like items to be attached to the head, such as hair and flocking hair. But you can. These hair-like products can be tried on and tried if you go to the store, but even if you cannot try on due to hygiene problems, or if you cannot order on the Internet or catalog, you can display the original skin color according to this embodiment. By comparing the unit 20 and the changed skin color display unit 21 visually, it is possible to select a hair-like article that realizes the desired skin color appearance.

  In the present embodiment, illustrations of human face shapes are used as the original skin color display unit 20 and the changed skin color display unit 21, but the present invention is not limited to this. For example, the changed skin color display unit 21 is a graph, chart, figure, table, or the like showing the correlation between the change in hair color when using a hair color changing material and the change tendency and degree of the skin color impression at that time. May be configured. Further, the change skin color display unit 21 may be displayed on the surface of the packaging container 16 or the storage package of the hair product 10 or may be stored in the storage package of the hair product 10 according to the instruction manual or the like. Moreover, it may be created and stored separately from the instruction manual.

  Moreover, this change skin color display part 21 may display or accommodate in transport containers, such as a storage case at the time of shipping several hair goods 10, and a cardboard box. Moreover, when displaying the hair goods 10 as a content of a website, you may display the change skin color display part 21 on the said content.

  Here, the three attributes of color will be described. The three attributes of color include hue, saturation, and lightness. By changing these, the appearance of the color changes. Details of the correlation between these three attributes of color and the appearance of skin color will be described later in the “Sensory Evaluation Experiment”, but for hue and saturation, the direction of change in hair color and the direction of change in appearance of skin color are described below. The inventors have found that there is a positive correlation between the two. On the other hand, the inventors have found that there is a negative correlation between the direction of change in hair color and the direction of change in the appearance of skin color. Therefore, by changing the hue, saturation or brightness of the hair color based on this knowledge, the appearance of the skin color can be changed as desired by the subject.

  That is, in the hair product 10 of the present embodiment, the difference between the original hair color display unit 30 and the changed hair color display unit 31 relating to the hue or saturation of the three attributes of the color, and the original skin color display unit 20 relating to the hue or saturation. And the difference between the changed skin color display unit 21 have an assimilation relationship.

  Further, the difference between the original hair color display unit 30 and the changed hair color display unit 31 relating to the lightness of the three attributes of the color and the difference between the original skin color display unit 20 and the changed skin color display unit 21 relating to the lightness are in a comparative relationship. Have.

In the present embodiment, the original hair color display unit 30 representing the hair color is displayed separately from the original skin color display unit 20, and the changed hair color display unit 31 representing the hair color changed using the hair color changing material. Is displayed separately from the change skin color display unit 21. However, the present invention is not limited to this. The original hair color display unit 30 and the original skin color display unit 20 may be arranged adjacent to each other, and the changed hair color display unit 31 and the changed skin color display unit 21 may be arranged adjacent to each other. At this time, the original hair color display unit 30 and the changed hair color display unit 31 may be displayed in a hairstyle shape, and the original skin color display unit 20 and the changed skin color display unit 21 may be displayed in a face shape. The hairstyle shape refers to a diagram schematically represented to the extent that it is recognized as a human hairstyle, or a photograph or a figure that faithfully represents the hairstyle. By adopting such a display mode, it is possible to know the change in the appearance of human hair and face color more realistically when the hair article of the present invention is used.
In this case, however, the color of the changed skin color display unit 21 may be set in consideration of the occurrence of an illusion effect between the changed hair color display unit 31 and the changed skin color display unit 21. For example, if the degree of the illusion effect between the changed hair color display unit 31 and the changed skin color display unit 21 generated in the packaging container 16 of the hair article 10 is larger than the amount of the illusion effect associated with the color change of the user's hair, the change The color difference between the skin color display unit 21 and the original skin color display unit 20 may be set smaller than that in the above embodiment. Thereby, in addition to the color difference between the changed skin color display unit 21 and the original skin color display unit 20, the influence of a large illusion effect generated between the changed hair color display unit 31 and the changed skin color display unit 21 is considered. For this reason, the user can suitably know the appearance of the skin color when his / her hair color is changed with the hair product 10 as the appearance color of the changed skin color display unit 21 when the packaging container 16 is viewed. .
In addition, when the degree of the illusion effect between the changed hair color display unit 31 and the changed skin color display unit 21 generated in the packaging container 16 of the hair article 10 is smaller than the amount of the illusion effect associated with the color change of the user's hair, On the contrary, the color difference between the changed skin color display unit 21 and the original skin color display unit 20 may be set larger than that in the above embodiment.

<Second embodiment>
Next, details of the second embodiment of the hair article 10 will be described with reference to FIG. FIG. 2 is a view showing a hair product (hair product group) 10 including a plurality of hair dye products 12 according to the second embodiment. Details will be described below.

  In FIG. 2, products A, B,... Are individual hair dye products 12. The storage package of the hair dye product 12 contains a hair dye (not shown). The plurality of hair dye products 12 such as the product A and the product B constitute the hair product 10 as a set. The hair product 10 is displayed on a display shelf and sold. As an example, the finished product color (dye color) is different for each product, such as product A is reddish brown, product B is yellowish brown, and the like. In addition, the dyed colors may be other than brown, such as black, red, blue, gold, and silver. Further, among the same tea-based dyed colors, a plurality of brown hair products 12 having different brightness and saturation may be used.

  Here, the global hue means that the hue is divided into basic colors of several steps to several tens of steps, and the saturation and lightness for each of these basic colors are further divided into several steps to several tens of steps. Refers to individual colors. Examples of basic colors include five levels of red, yellow, green, blue, and purple. In addition, ten levels of red, yellow-red, yellow, yellow-green, green, blue-green, blue, purple-blue, purple, and magenta may be set as basic colors. The color tone refers to the strength of the basic color in each of these global colors.

  The brown hue is orange (yellow red). In other words, the orange with reduced saturation and lightness is brown. Then, by further reducing the lightness of brown, it approaches the so-called black hair color. Therefore, the basic color of black or brown hair is yellow-red. For this reason, in the case of black or brown hair, it is possible to change the hair color to a natural color without changing the overall hue of the original hair color by adjusting the yellowness or redness.

When the original hair color for each user is different, the changed hair color when using a common hair dye is naturally different. When the color of the hair dye is brown, the lightness of the changed hair color increases when the original hair color is black, and conversely, the lightness of the changed hair color decreases when the original hair color is gray or white. It becomes.
Further, even when the original skin color for each user is different, the skin color impression (changed skin color) after application of the hair dye is naturally different.
The hair article 10 of the present embodiment makes it possible for a large number of users having different original hair colors and original skin colors to appropriately know the impression change of the changed skin color and the suitability of the changed skin color and the changed hair color. Can do.

  In the hair article (hair article group) 10 of the present embodiment, the first original skin color display part 20a and the second original skin color display part 20b having different skin colors, the first original skin color display part 20a and the second original skin color display part 20a. The first change skin color display part 21a and the second change skin color display part 21b respectively corresponding to the original skin color display part 20b are displayed.

  Although not shown, one or a plurality of hair dyes are stored in the storage package of each hair dye product 12 of the present embodiment. As described above, the dyed colors of the products A, B,... Of the present embodiment are the same tea, but the brightness, saturation, and hue are little by little, such as red, orange, yellow, and ash. Different. As shown in FIG. 2, a plurality of hair color display portions 30 are displayed on the surface of the storage package of the hair dye product 12 of the product A. In the present embodiment, patterns of four colors of (1) black, (2) brown, (3) gray, and (4) white are individually displayed as the base hair color display unit 30 as the base hair color assumed as the user. Has been. Each pattern is displayed so as to be distinguished from each other. Corresponding to each color of the original hair color display unit 30, a changed hair color display unit 31 a indicating a changed hair color when the hair dye product 12 of the product A is used is displayed on the hair dye product 12. The original hair color display unit 30 and the changed hair color display unit 31a are connected by an index (arrow) indicating that the hair color has changed from the original hair color display unit 30 to the changed hair color display unit 31a.

  Similarly, regarding the product B, the four hair color display portions 30 are displayed apart from each other, and the hair dye product 12 of the product B is used corresponding to each color of the hair color display portion 30. A changed hair color display portion 31 b indicating the changed hair color is displayed on the hair dyeing product 12.

  As an example, it is assumed that the dyed color of the hair dye product 12 of the product A and the product B has an intermediate brightness between (2) brown and (3) gray. In this case, when such a hair coloring product 12 is used to change the hair color, the brightness of the original hair color of (1) black and (2) brown increases (3) gray and (4) white The lightness of the original hair color decreases.

  Furthermore, in the hair dye product 12 of the product A, the degree of change in the appearance of the skin color due to the illusion effect when the original hair color becomes a changed hair color in the four patterns (1) to (4). The first original skin color display portion 20a and the first changed skin color display portion 21a are displayed as the color difference. Specifically, the lightness of the original skin color decreases as the contrast (illusion) effect by increasing the lightness of the original hair color of (1) black and (2) brown by the use of the hair dye product 12. That is, for the patterns (1) and (2), the brightness of the first changed skin color display unit 21a is smaller than the brightness of the first original skin color display unit 20a. On the contrary, regarding the patterns of (3) gray and (4) white, the lightness of the hair color is reduced by the use of the hair coloring product 12, and therefore the brightness of the first change skin color display part 21a is It is larger than the brightness of one original skin color display portion 20a. The same applies to the product B. Therefore, the user can visually confirm his / her changed skin color before actually using the product.

  In the present embodiment, as shown in FIG. 1, the first original skin color display unit 20a and the second original skin color display unit 20b individually display symbols for each of the four patterns (1) to (4). ing. The four symbols constituting the first original skin color display unit 20a may be the same color or different colors. Instead of this embodiment, one symbol may be displayed in common for each pattern. The same applies to the second original skin color display portion 20b.

  And the 1st original skin color display part 20a and the 2nd original skin color display part 20b may be a common color over several goods from which the dyeing color by the hair dye product 12 differs. Thereby, the user having the original skin color can know both the changed skin color when the product A is used and the changed skin color when the product B is used.

  Regarding the hair product 10 described above, two specific procedures for the user to select a product are illustrated.

  As a first example, a case is assumed in which the user designates a global hue of a dyed color and confirms the suitability of the dyed hair in advance. As a specific example, assume that the dyed color is reddish brown. In this case, the product A having the desired dyeing color is selected, and the original hair color display unit 30 displayed on the product A is referred to.

  When the original hair color display unit 30 close to the user's original hair color is found from the patterns (1) to (4), the first original skin color display unit 20a and the first changed skin color display unit corresponding to the pattern It can be seen that the color difference from 21a occurs as an illusion effect on the user's original skin color. When the user's original skin color is close to the color of the first original skin color display unit 20a, the color of the first changed skin color display unit 21a corresponds to the user's changed skin color. Thereby, the user can know whether or not a desired skin color is realized by using the product A.

  Next, as a second example, a case is assumed in which the overall hue of the dyed color of the hair is not particularly limited, and a skin color impression (changed skin color) after the hair color change is realized as desired. For example, assume that the user's original hair color is black. The user extracts one or a plurality of products A, B,... In which the original hair color display unit 30 and the original skin color display units 20a and 20b close to the user's original hair color and original skin color are displayed. To do. In addition, it is preferable to select a product whose change skin color displayed on the change skin color display portions 21a and 21b is the most desired color.

  As described above, in the present embodiment, the case where the basic hair colors displayed as the basic hair color display unit 30 on the hair dyeing product 12 are the basic colors of black, brown, gray, and white are illustrated. All of these four hues are yellow-red. However, there is no strictly achromatic hair color, and Japanese hair color tends to be a little brownish, even among blacks. Brown also has individual differences from dark brown to light brown, and even gray, there are many variations such as gray density varies depending on the individual depending on the ratio of white hair to black hair. Therefore, the basic four-color hair color display unit 30 may be displayed on the storage package, and the appearance change information (detailed change information) of many other hair colors may be displayed separately. Specifically, it may be printed on an instruction manual or the like and stored inside the storage package, or in the form of a booklet, poster, pop, etc. near the retail store of the hair product 10 or the seat of a beauty salon. Detailed change information may be exhibited at

<Sensory evaluation experiment>
Next, the sensory evaluation experiment that led to the completion of the present invention will be described. From this experiment, it is qualitatively confirmed that the appearance of the face skin color changes by changing the hair color, and the difference in color between the original skin color display unit 20 and the changed skin color display unit 21 is quantitatively determined. It became possible to do.

(Experimental example 1)
(1) Creation of an image with changed hair color (hair color changed image) First, a plurality of images with different hair colors were created without changing the skin color of the face of the reference image. Specifically, a full-color reference image (digital image) of the sample provider's face was prepared, and the hair region was designated in this reference image. Next, the average hue (H) of the hair region was periodically expressed from 0 to 360, and the saturation (S) and lightness (V) were expressed from 0 to 100. Furthermore, a hair color change image was created by changing the values of the three attributes of the color of the hair region. The designation of the region of the hair and the change in the three attributes of the color of the region can be performed using the method described in Patent Document 3 above.

  The creation results are shown in Table 1 below. Note that the brightness is expressed as positive (plus) when the brightness is higher than that of the reference image, and is expressed as negative (minus) when the brightness is low. As for the saturation, a higher saturation than the reference image is expressed as positive (plus), and a lower saturation is expressed as negative. Further, regarding the hue, making the hair color yellowish than the reference image is expressed as increasing the hue, and the positive (plus) direction of the hue. Conversely, to make the hair color more reddish than the reference image is expressed as a lower hue, and is in the negative (minus) direction of the hue.

(2) Creation of an image with different skin color (skin color change image) Next, a plurality of skin color change images were created in which the skin color of the face was changed as follows without changing the hair color of the reference image. . The designation of the skin region and the change of the three attributes of the color of the region can also be performed using the method described in Patent Document 3 above.
(2-1) Hue In the same reference image as used in (1), the skin area of the face is designated in advance, and the average hue (H) of the skin area is as shown in Table 2 below. The images were changed from the reference image in 10 increments of 1.0. Saturation and lightness were constant.

(2-2) Saturation In the reference image used in (1), the skin area of the face is specified in advance, and the average saturation (S) of the skin area is as shown in Table 3 below. Images changed from the reference image in 10 increments every 0.25 were created. Hue and brightness were constant.

(2-3) Lightness In the reference image used in (1), the skin area of the face is designated in advance, and the average lightness (V) of the skin area is as shown in Table 4 below. The images were changed in 10 increments from 0.65. Hue and saturation were constant.

(3) Sensory evaluation experiment FIG. 3 is a schematic diagram of an evaluation test image in which the hair color change image created in the above (1) and the skin color change image created in the above (2) are arranged side by side for comparison. It is. A sensory evaluation experiment was conducted in which five test subjects, who are beauty specialists (beauticians), visually recognized the evaluation test images and selected images that looked the same skin color in both images. Specifically, the drawings from (1) to (n) in FIG. 3 show the hair color brightness + 4 image and the hair color brightness-4 hair color change image shown in Table 1 (two types: FIG. 3). The left side), and the skin color change images of skin color lightness changes 1 to 10 shown in Table 4 and the reference images (11 ways in total: right side in FIG. 3) are 22 evaluation test images arranged in combination. As described above, the hair color change image is a group of images in which only the hair color is changed with the skin color unchanged, and the skin color change image is a group of images in which only the skin color is changed with the hair color unchanged.

  Then, the above five test subjects were allowed to visually check 22 kinds of evaluation test images, and the two images to be compared were selected to have the same skin color. That is, the appearance of the skin color viewed in the image of the hair color lightness +4 or the hair color lightness −4 in which the lightness of the hair color is changed is the same as the appearance of the skin color in the reference image, or the lightness of the skin color is set. It was investigated whether the skin color change image was changed to the same appearance as any of the skin colors.

  Similarly, regarding the hue, the hair color change image (Table 1: 2 types) in which only the hue of the hair color of the reference image is changed to +10 or −10, and only the hue of the skin color of the face of the reference image are also changed. Twenty-two evaluation test images were prepared (not shown) in which the skin color change image and the reference image (Table 2: 11 types in total) were combined and arranged individually. Then, the five test subjects were made to visually check the evaluation test image, and the two images to be compared were selected to have the same skin color. Thereby, the appearance of the skin color viewed in the image of the hair color hue +10 or the hair color hue −10 in which the hue of the hair color is changed is the same as the appearance of the skin color in the reference image, or the skin color hue It was investigated whether the skin color change image obtained by changing the skin color looks similar to one of the skin colors.

  Similarly, with regard to the saturation, similarly to the hair color change image (Table 1: 2 types) in which only the saturation of the hair color of the reference image is changed to +7 or -8, the saturation of the skin color of the face of the reference image is also the same. Twenty-two evaluation test images were prepared (not shown) in which only the skin color change image and the reference image (Table 3: total 11 types) were changed and arranged individually in combination. Then, the five test subjects were made to visually check the evaluation test image, and the two images to be compared were selected to have the same skin color. As a result, the appearance of the skin color viewed in the image of the hair color saturation +7 or the hair color saturation −8 in which the saturation of the hair color is changed is the same as the appearance of the skin color in the reference image, or the skin color It was investigated whether the skin color change image in which the saturation was changed looks the same as any of the skin colors.

(4) Evaluation results Table 5 below shows the results of quantification of changes in the appearance of skin color based on the results of the above sensory evaluation experiment by changing the hue, saturation, and lightness of the hair color. .

  Based on the results of Table 5 above, the results of plotting the amount of change in the appearance of skin color (average value of five subjects) against the amount of change in hair color are shown in FIGS. 4, 5, and 6. Since the amount of change in the appearance of the skin color when the hair color is not changed is zero, the regression line was obtained under the condition of passing through the origin in the graphs of FIGS. From these results, the change in the appearance of the skin color (vertical axis: Y) with respect to the change in hair color (horizontal axis: X) shows that the hue and saturation are in an assimilation relationship (positive correlation), on the contrary Was found to be in a correlation (negative correlation).

  Based on the results of Experimental Example 1 described above, with respect to hue or saturation, the direction of change in hair color and the direction of change in the appearance of skin color are associated with each other with a positive correlation. With regard to lightness, the direction of change in hair color and the direction of change in the appearance of skin color are associated with each other with a negative correlation.

  For this reason, the change degree of a skin color impression can be quantitatively acquired by changing hair color as mentioned above using a hair dye. For this reason, since the suitability of the hair color can be determined based on the appearance of the changed skin color instead of the original skin color, the suitable hair color desired by the user can be accurately realized. The user can change the appearance of the skin color as desired by changing the hair color. For this reason, in addition to actually changing the skin color by makeup or the like, it is possible to change the appearance of the skin color as desired by utilizing the change in the hair color.

  FIG. 4 to FIG. 6 described above change the amount of change in hair color (hue, saturation, and lightness) and how the skin color (hue, saturation, and lightness) changes according to the amount of change in the hair color. It is a graph showing quantity. Therefore, by referring to the graph, it is possible to obtain the skin color impression change amount (skin color change amount) based on the hair color change amount when the hair color changing material is used. And the color of the change skin color display part 21 can be determined by adding this skin color change amount with respect to the original skin color display part 20 of a predetermined color.
