DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of selecting a point makeup cosmetic, and more particularly, to a method of selecting a point makeup cosmetic that matches the skin color of the face.

[0002]

2. Description of the Related Art Point makeup cosmetics such as lip colors are makeup cosmetics that play an important role in accentuating the face and forming an image of the person. Therefore, point makeup cosmetics have a very large variety of colors, and there are not a few point makeup cosmetics far from skin color. For this reason, it has been very difficult to select a point makeup cosmetic of a color suitable for the user, that is, in harmony with the skin color of the user.

On the other hand, regarding color harmony, Moon and S
Pencer's theory of color harmony and disharmony is known, but the relationship between skin color and point makeup color is evaluated based on this theory, and all point makeup for any skin color is evaluated. This theory cannot be used as a criterion for the selection of point makeup cosmetics, as this would result in a harmonious cosmetic.

[0004] Reflecting such a situation, when selecting point makeup cosmetics, the user selects several colors from a color sample filled with a small amount of point makeup cosmetic of each color. Methods for trial use and selection of a point makeup cosmetic to be finally used are widely performed. However, the selection criterion in such a selection method is a user's own preference or judgment, and it is not possible to know how others feel, and a specific trial is used from many color samples. The problem was that the task of selecting the colors was extremely difficult.

[0005] In addition, there is a method using a demonstration using a makeup simulator as a method for selecting point makeup cosmetics, but this method is not very versatile because the equipment is large and expensive.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above point of view, and provides a simple and objective selection of point makeup cosmetics having a color in harmony with the skin color of the user's face. It is an object to provide a method for performing the above.

[0007]

Means for Solving the Problems In order to solve the above problems, the present inventors have conducted intensive studies on the relationship between the harmony and the disharmony between the skin color of the face and the color of the point makeup cosmetic. The present inventors have found that the difference in brightness between the two is closely related to harmony and disharmony, and completed the present invention.

[0008] That is, the present invention is characterized in that the color of the face skin and the point makeup cosmetic of the user of the point makeup cosmetic are measured, and the point makeup cosmetic is selected using the brightness difference between the two as an index. This is a selection method of point makeup cosmetics.

Hereinafter, the present invention will be described in detail. According to the method for selecting a point makeup cosmetic of the present invention, the index is a brightness difference between the skin color of the user's face and the color of the point makeup cosmetic. In order to establish a selection method of makeup makeup, the following contents were investigated using lip color as point makeup makeup.

(1) Relationship between the skin color of the face of the cosmetics user and the color of the lip color Ten photographs of five models having the skin color of the face shown in the upper part of Table 1 are prepared. Various lip colors shown in the lower part were respectively applied to prepare sample photographs for evaluation. Table 1 shows Munsell values obtained by measuring the skin and lip color of the photographic model used for evaluation using Munsell color coordinates as a color system.

[0011]

[Table 1]

In the lip color symbol, the first number indicates the hue (1 is 1.25 RP, 2 is 5 RP,
3 is 8.75 RP, 4 is 10 RP, 6 is 6.25 R
, 9 represents 3.75 YR, respectively), the next number represents the lightness as it is, and the last alphabet or number represents the saturation (A represents 10, E represents 14, and 8 represents 8 as it is). .

With respect to the evaluation sample photographs obtained as described above, 137 panelists randomly selected were asked to determine whether or not the color of the lip color was in harmony with the skin color of the face of the model. They were evaluated on a 5-point scale based on the criteria shown, and the results were filled out on a questionnaire.

1: Not at all 2: Not at all 3: Neither 4: Attentive 5: Attentive

[0015] First, 13
The percentages of the seven panelists by age and gender are shown in the pie chart (Fig. 1). From this, it is clear that the panelists in this study have no gender or age variation.

Next, the results of the questionnaire are shown in Tables 2 to 6 and FIGS. Tables 2 to 6 show the average values of the scores of 137 persons of each lip color for each model of fair white (high lightness) intermediate color, dark black (low lightness) intermediate color, medium lightness pink system, medium lightness intermediate color, and medium lightness ocher system. And the matching rankings assigned in descending order of the scores.

[Table 6]

FIG. 2 is a diagram showing, on a hue circle, the relationship between the hue and saturation of the lip color and the order in which the lip color matches when the skin color of the model is a medium-brightness intermediate color. The hue circle in the figure is created according to the Munsell color chart, and the distance from the center of the circle represents the saturation (saturation increases as the distance from the center increases). In the figure, the symbol ■ indicates the position of the skin color of the model on the color wheel, the symbol 位置 indicates the position of each lip color on the color wheel, and the numbers near the symbol を indicate the matching rank obtained from the average score of the lip color. And the color symbol of the lip color is shown in parentheses beside it. From this figure, it can be seen that there is no specific relationship between the hue and saturation of the lip color and whether or not the lip color matches.

FIGS. 3 to 7 show the lightness, saturation, and lip of the skin color of each of the white (high lightness) intermediate color, black (low lightness) intermediate color, medium lightness pink system, medium lightness intermediate color, and medium lightness ocher system models, respectively. FIG. 6 is a diagram illustrating a relationship between a difference between a lightness and a saturation of a color (a lightness difference and a saturation difference) and an order in which a lip color matches. Here, both the lightness difference and the saturation difference are values obtained by subtracting the model skin color value from the lip color value.

3 to 7, the vertical axis represents the lightness difference, the horizontal axis represents the saturation difference, and ● represents the coordinate position of each lip color.
The number near the mark indicates the matching rank obtained from the average score of the lip color, and the color symbol of the lip color is shown in parentheses. From these figures, it can be seen that the rank or score that matches the lip color has almost no relation to the saturation difference between the skin color of the face and the color of the lip color in any model, that is, in any skin color. It has been found that the lightness difference between the skin color of the face and the color of the lip color has the following relationship.

In other words, if the lightness difference obtained by subtracting the lightness of the skin color of the face from the lightness of the color of the lip color is a negative value, the ranking or score suitable for the lip color is high, and the lightness difference takes a positive value. If the lip color matches or has a lower score, in other words, if the color of the lip color is darker than the user's skin color, the color of the lip color generally matches the user's skin color, and the color of the lip color If the color is lighter than the user's skin color, the color of the lip color does not match the user's skin color.

Furthermore, as a result of a detailed analysis of the relationship between the above-mentioned brightness difference and the rank and rating of the lip color, if the following two points are taken into consideration, the ranking and score of the brightness difference and the lip color are well correlated. Specifically, it was found that the smaller the value obtained by subtracting the lightness value of the skin color of the face from the lightness value of the color of the lip color is smaller, the higher the ranking and the higher the score of the lip color. From this relationship, if the lightness difference is -1 or less, it can be said that the color of the lip color is well harmonized with the skin color of the user. It can be understood that they are in harmony, and when the brightness difference exceeds 0, it can be determined that they are not in harmony.

Here, one of the two points to be taken into consideration is a lip color rank or score and a skin color of a face based on the lip color lightness for a skin color model of fair white (high lightness). Is not very strong. This is considered to be because the fair-skin (high-brightness) intermediate color skin color model has obtained a relatively good score for any lip color, and there is not much difference between the lip colors.

Another point is that, for a lip color that is rarely used in practice and has a small chroma difference between the skin color of the face and the color of the lip color, the lightness difference and the rank are not necessarily correlated. It is.

From the above results, whether the lip color is in harmony with the user's skin color is independent of the user's skin color and irrespective of the hue and saturation of the lip color. It was found that the following judgment can be made based on the lightness difference between the color and the user's skin color.

If the lightness difference obtained by subtracting the lightness of the skin color of the face from the lightness of the color of the lip color measured using the Munsell color coordinates as a color system is a negative value, the color of the lip color is substantially in harmony with the skin color of the user. If the lightness difference is a positive value, the lip color does not match the user's skin color. Furthermore,
If this brightness difference is -1 or less, the color of the lip color is
It is in harmony with the user's skin tone.

(2) Method for selecting point makeup cosmetics of the present invention The method for selecting point makeup cosmetics of the present invention is based on the knowledge obtained from the above survey results.
It is characterized in that the skin of the user and the point makeup cosmetic are measured in color, and a preferable color of the point makeup cosmetic is selected using the brightness difference between the two as an index.

The point makeup cosmetic to which the selection method of the present invention is applied is not particularly limited as long as it is a cosmetic usually used as a point makeup cosmetic. For example, lip color, cheek color, eye, etc. Colors and the like can be mentioned, and among these, lip colors can be mentioned as point makeup cosmetics that can be more effectively selected by the selection method of the present invention.

The method of measuring the color of the user's skin or point makeup cosmetics is not particularly limited, and is usually performed by using the usual method, specifically, the color coordinates of Munsell shown in the above experiment. In a method of knowing the absolute positional relationship of a color or a method of measuring a color difference with respect to a certain color and observing a difference in lightness, for example, measuring a color difference with XYZ coordinates and expressing a Y value as a color difference using Lab is represented by L. A method of checking the brightness difference using the value can be used. Furthermore, as a simpler method,
A method of comparing colors using a color chart can be used in the present invention.

As described above, in the selection method of the present invention, it is possible to measure the color of the point makeup cosmetic user's skin and the point makeup cosmetic by various methods. Is preferably used as a colorimetric system.

In the method for selecting a point makeup cosmetic of the present invention, the lightness of the color of the point makeup cosmetic measured by each of the above methods is compared with the lightness of the skin color of the user of the point makeup cosmetic. If the lightness of the color of the point makeup cosmetic is lower (darker) than the lightness of the skin color of the user, the point makeup cosmetic will be in harmony with the skin color of the user. In addition, when the lightness of the color of the point makeup cosmetic is higher (brighter) than the lightness of the skin color of the user, the point makeup cosmetic does not match the skin color of the user.

For example, when colorimetry is performed by a colorimetric method using Munsell color coordinates, which is a preferred colorimetric method in the present invention, as a color system, the skin color is obtained from the lightness value of the color of the obtained point makeup cosmetic. The value obtained by subtracting the lightness value of this item gives a negative impression that the point makeup cosmetic gives a favorable impression to others when used, and is evaluated as being suitable.

Further, when comparing the lightness value of the color of the point makeup cosmetic and the lightness value of the skin color when the color is measured using the Munsell color coordinates as a color system, the lightness value of the color of the point makeup cosmetic is It is judged that the point makeup cosmetics whose value obtained by subtracting the lightness value of the skin color from -1 is not more than -1 is well suited, and conversely, it is judged that they are not well suited when this value takes a positive number. It is. In the range where the difference in lightness between these values is more than −1 and equal to or less than 0, it is determined that the point makeup cosmetic suits the skin color of the user to some extent.

[0038]

Embodiments of the present invention will be described below. Using the photographs of the four models with different skin colors and the five types of lip colors shown in Table 7, sample photographs for evaluation were prepared in the same manner as in the above investigation. Note that the Munsell values in Table 7 are values obtained by measuring the skin and lip color of the face of each model using the Munsell color coordinates as a color system.

[0039]

[Table 7]

The above sample picture for evaluation was shown to 17 panelists, and asked by a questionnaire to judge “fit” or “not fit”. The judgment was made based on the following criteria as in the above investigation.

1: Not at all 2: Not at all 3: Neither 4: Attentive 5: Attentive

On the other hand, whether or not the colors of various lip colors are in harmony with the skin color of each model is determined by subtracting the lightness of the skin color of the model from the lightness of the lip color by the Munsell value used in the selection method of the present invention. Judgment was made separately based on the following criteria from the brightness difference.

◎: Brightness difference is -1.0 or less and well conformed.: -1.0 <brightness difference ≦ 0, somewhat conformable. X: Brightness difference exceeds 0. Table 8 shows the results.

[0044]

[Table 8]

From these results, it can be seen that the judgment of the suitability of the color of the lip color to the skin color of the user based on the selection method of the point makeup cosmetic of the present invention and the score of the questionnaire agree well. From this, the accuracy of the selection method of the present invention is clear.

[0046]

According to the selection method of the present invention, a point makeup cosmetic having a color in harmony with the skin color of the user's face can be obtained.
Selection can be made simply and objectively.
