Abstract

PROBLEM TO BE SOLVED: To easily and precisely select a suitable color even for the person who has no experience by opening the viewing window sections straddling over at least two colors in a color sample sheet in which approximate plural colors are arranged on its surface. SOLUTION: The cards are grossly classified into color sample sheet groups 6 which belong to different color images. Moreover, within the groups 6, which belong to the same color image, the groups 6 are classified into different color hue groups, based on the differences in color hue. Then, color sample sheets 1 are finely classified into the groups which have a same color hue but, have a different color tint. If one wishes to find the color, to which a color sample belongs, he selects the sheet 1, which displays the color sample that approximates the color, from a plurality of sheets 1. Then, a color sample is abutted on a viewing window section 3 of the sheet 1 from the back side, and the color of the color sample positioned at the section 3 and the colors which the located adjacent to the section 3 on the surface of the sheet 1 can be compared with each other. Thus suitable color is selected while comparing the plural colors which are appropriate to each other.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color sample card.

[0002]

2. Description of the Related Art Conventionally, when selecting a target color from colors such as color samples, it has been performed by comparing the color samples with the colors displayed in a color sample book one by one. However, there is a problem that colorimetry is difficult, and a person without specialized knowledge or experience cannot select a corresponding color with high accuracy.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and easily and accurately selects a corresponding color without any special knowledge or experience. It is an object of the present invention to provide a color swatch card that can be used.

[0004]

In order to solve the above-mentioned problems, a color sample card according to the present invention is provided with a viewing window portion extending over at least two colors on a color sample sheet 1 in which a plurality of colors similar to the surface are arranged and arranged. 3 is opened. With this configuration, the color sample 4 is brought into contact with the viewing window 3 from behind, so that the color of the color sample 4 located in the viewing window 3 and the color located on both sides of the viewing window 3 are arranged. The color of the adjacent color sample 5 displayed on the surface of the sample sheet 1 can be compared with each other, and the corresponding color can be selected while simultaneously comparing a plurality of similar colors.

It is also preferable that a plurality of card-like color sample sheets 1 be stacked one on top of the other and bound in a booklet form, and be opened like a fan. With such a configuration, not only can it be used for each page by spreading out in a fan shape, but also colorimetry can be performed on a plurality of pages at the same time.

[0006]

Embodiments of the present invention will be described below with reference to the accompanying drawings. The color sample sheet 1 is in the form of a card, and a plurality of colors approximating the surface of the card-shaped color sample sheet 1 are arranged and arranged to form a plurality of color samples 5 (5a,
5b, 5c, 5d,...) Constitute a color sample card. The color sample sheet 1 constituting the main body of the color sample card has an opening window 3 for straddling at least two or more color samples. In the embodiment shown in FIG. 2, an example is shown in which the viewing window portion 3 is provided so as to open over the color sample 5 of two colors, but the viewing window is provided so as to extend over the color sample 5 of three or more colors. The window 3 may be formed.

[0007] The color sample sheet 1 having the above structure is shown in FIG.
A plurality of sheets are stacked one above the other and one end is bound by a shaft 8 so that the door can be opened like a door. 9 in the figure
Is a display sheet, which is bound on the uppermost layer as a cover when a plurality of the color sample sheets 1 are bound. Here, in the embodiment of FIG. 1, the color sample sheet group 6 belonging to the image of different color is roughly classified, and further, the color sample group 6 belonging to the image of the same color has different hues due to the difference in hue. Each color sample sheet 1 is classified into groups, and the hue is the same, but the color is different.
Is subdivided. In each of the color sample sheets 1, a plurality of color samples 5 having the same hue and saturation but different lightness are displayed in a line.

In selecting a color of the color sample 4, a color sample sheet 1 displaying an approximate color sample 5 is selected from a plurality of color sample sheets 1, and the color sample sheet is selected. A color sample 4 is applied to the viewing window 3 from behind, and the color sample 4 located in the viewing window 3 is placed.
Color sample sheets 1 located on both sides of the viewing window 3
Can be compared with the colors of the adjacent color sample 5 displayed on the surface of the image, and the corresponding color can be selected while simultaneously comparing a plurality of similar colors. For example, in the case of FIG. 3, color samples 5a and 5b are located on both sides of the color sample 4 located in the slit window 3a, and color samples are located on both sides of the color sample 4 located in the slot window 3b. 5b, 5
c is located and the color samples 5c and 5d are located on both sides of the color sample 4 located in the slotted window 3c, so that the colors of the color sample 4 and the color samples 5a and 5b can be colorimetric simultaneously.
In addition, the color of the color sample 4 and the colors of the color samples 5b and 5c can be simultaneously compared, and the color of the color sample 4 and the colors of the color samples 5c and 5d can be simultaneously compared with each other. However, even an inexperienced person can easily select the corresponding color with high accuracy. In particular, for example, when the colors of the color sample 4 and the color samples 5a and 5b are simultaneously colorimetrically compared, the color difference in the portion surrounded by the broken line B in FIG. So
A subtle color difference can be accurately determined.

When the color sample sheet 1 is opened in a fan shape about the axis 8 and the color of the color sample 4 is selected as described above, it can be used for each page as well as at the same time. Colorimetry can be performed on multiple pages. By selecting colors as described above, for example, color coordination of the interior and exterior of a building can be performed.

In the above-described embodiment, an example is shown in which the color sample sheets 1 are roughly classified into color sample sheet groups 6 belonging to images of different colors. Here, all colors are converted into images of a plurality of colors. A method of sorting and grouping will be described. FIG. 8 shows “hue”, which is called three attributes of color.
FIG. 3 is a three-dimensional diagram of hue, lightness, and saturation in which three elements of “brightness” and “saturation” are considered as a solid with hue as an outer periphery, brightness as a vertical axis, and saturation as a horizontal axis from the center. The chromaticity diagram of the Munsell color system can be represented by a Munsell color chart, and this Munsell color chart has three values of saturation and lightness in an arbitrary hue.
The relationship between the elements of the two color attributes can be represented by numerical values. FIGS. 4A and 4B each show an example of the Munsell color chart 21. In FIG. 4A, 7R is a symbol defined in the Munsell hue circle (R is an abbreviation for Red (red)). In the Munsell color chart 21, C is saturation, V
Indicates lightness. Then, assuming that the hue of the target sample color to be determined is 7R, the lightness is 6V, and the saturation is 7C, this color is represented by a circle in the Munsell color chart 21 of the hue 7R shown in FIG. Can be determined to be located at the address. That is, in FIG. 4A, the color at the position ○ can be represented by a numerical value (7R, 6V, 7C). Similarly, in the Munsell color chart 21 of the hue 6YR (YR is an abbreviation of Yellow Red) in FIG.
R, 5V, 4C). Of course, the sample color is not only represented by integers for both lightness and saturation, but also has a decimal point, for example, (7R, 6, 2
V, 7, 5C) and the like.

Then, utilizing the technique of expressing the color of the target sample to be determined as a numerical value as described above,
Further, in addition to this, the chromaticity diagram (Munsell color chart 21 in the embodiment) is zoned by a color image,
It is determined which zone the target sample color belongs to in the zone of the color image on the chromaticity diagram.

When performing zoning based on color images, zoning is performed using a plurality of different or target color images. For example, zones are divided into, for example, an image of a color "warm" and an image of a color "refreshing". Now, an example in which zones are divided into an image of a color “warm” and an image of a color “refreshing” will be described. Hues are divided into an arbitrary number in the Munsell hue circle (for example, divided into 100 hues). As many Munsell color patches 21 are formed. In this case, the lightness and saturation of each Munsell color chart 21 are also divided into arbitrary plural stages (each Munsell color chart 2).
In FIG. 1, the brightness is divided into eight levels of 2 to 9 and the saturation is divided into 13 levels.

Next, for each color chart, that is, for each of the 100 types of Munsell color charts 21 in the embodiment, a zone A of a color image of "warm" and a zone B of an image of color "fresh" are formed. What separates. 5 to 7
FIG. 2 illustrates a plurality of examples of the Munsell color chart 21 divided into the above-mentioned image of the color "warm" and the image of the color "fresh". That is, FIGS. 5 to 7 show that the hues are 6R, 6YR, and 10Y (where Y is Yellow).
An example is shown in which the Munsell color chart 21 (abbreviated as w) is zoned into an image of a color “warm” and a color of “fresh”. In FIGS. 5 to 7, the zone A of the image of “warm” is indicated by cross hatching for convenience, and the zone B of the image of “fresh” is hatched.

As described above, in dividing each of the Munsell color charts 21 into the zone A of the image of the color "warm" and the zone B of the image of the color "fresh", the colors of a large number of sample colors are determined in advance. And set whether the color of the sample is classified into an image of a color “warm” or an image of a color “refreshing”. The color of the sample is digitized as described above to determine which address of which Munsell color chart 21 is located. In this manner, the lightness number and the saturation number of the Munsell color chart 21 for each hue are obtained. By performing the work of determining which image is the color of the address to be represented, the Munsell color chart 21 can be obtained.
Each zone can be divided into a zone A of an image of a color “warm” and a zone B of an image of a color “refreshing”.

In setting whether the colors of the large number of samples are classified into the image of the color "warm" or the image of the color "fresh", the designer of the building, the designer of the interior, etc. Experts, or an unspecified number of people, to determine whether the color of each sample is "warm" or "fresh" image, or
Conventionally, in the design of a building or interior, a color that has been used as a color of a “warm” image or a color that has been used as a color of a “fresh” image is used as it is for the above-described zoning.

As described above, for each Munsell color chart 21 (in the embodiment, the hue is divided into 100 hues in the Munsell hue circle, so for each 100 Munsell color chart 21), the image of the color "warm" is displayed. The data divided into the zone A and the zone B of the image of the color "fresh" is stored as a memory in a computer (not shown).

On the other hand, the computer is connected to a colorimeter (not shown) for reading a sample color to be determined and digitizing the sample color. As the colorimeter, a conventionally known one can be adopted (for example, there is a "colorimeter manufactured by Minolta Camera Co., Ltd."). Thus, in the present embodiment, in order to determine which image zone a sample color belongs to, the colorimeter is applied to a sample, the sample color is read by the colorimeter, digitized, and digitized. In determining which address of each Munsell color chart 21 stored in the computer the sample color is located in, data obtained by zoning each Munsell color chart 21 (that is, in the embodiment, "warm" for each Munsell color chart 21) Is automatically classified based on the data obtained by dividing the image into a zone A having a color of “A” and a zone B having an image having a color of “refreshing”. To display.

In this manner, all the sample colors to be determined are read by the colorimeter 3 and quantified, and based on data of the quantified sample colors, any one of a plurality of images whose colors are set is determined. Can automatically be determined. In this way, the colors are divided into, for example, a “warm” image color and a “fresh” image color, whereby each color is displayed on the color sample card 1 of the card group 6 of the “warm” color image. It is determined whether the color belongs to the color to be displayed or the color displayed on the color sample card 1 of the card group 6 of the image of the "warm" color.

According to the invention of claim 1 of the present invention, as described above, a viewing window portion extending over at least two colors is provided on a color sample sheet in which a plurality of colors similar to the surface are arranged and arranged. Since there is an opening, by applying a color sample or the like to the opened viewing window from the back side, it is easy for even inexperienced people to select the appropriate color while comparing multiple similar colors at the same time. Can be done.

According to the second aspect of the present invention, in addition to the effects of the first aspect of the present invention, a plurality of card-shaped color sample sheets are stacked one on top of the other and bound in a booklet shape and fan-shaped. Because it can be spread freely, it is not only compact and easy to handle, it can be used for each page by opening it in a fan shape, and it is possible to perform colorimetry on multiple pages at the same time, improving usability Things.
