Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a color scheme selection tool for the purpose of easily determining whether the harmony of two-color combinations is good or bad, and it is widely used in fields that deal with colors. It is something that will be done.

(Prior art) Conventionally, to indicate the quality of two-color harmony, a plurality of color chart pairs are fixed to a base plate, one side of the color chart pair is all the same reference color, and the other side is a different color. It is known that colors are ranked in order of magnitude of visual color difference (Utility Model Publication No. 58-10122).

(Problems to be solved by the invention) According to the above-mentioned conventional technology, the quality of a two-color combination can only be understood as a point in terms of the relationship between two specific colors; It was not possible to understand this as an area with a certain range. Therefore, according to the conventional technology, it is necessary to individually express the quality of harmony with other colors for each reference color, and an extremely large number of base plates are required. Another problem was that it was not possible to judge the quality of the color scheme for colors that were not displayed on the base plate, especially for colors that were outside the range displayed on Munsell's color chart.

(Means for solving the problem) The color scheme selection tool of this invention displays the harmoniousness of the combination of any reference color with the color displayed on the Munsell color chart in correspondence with the Munsell color chart. It is made up of a combination of transparent plate and Munsell's color chart.

The degree of harmony may be determined by excluding the hue of the reference color and performing data processing based on the difference between brightness and saturation (based on the Munsell value). The reason for adopting this method is that while it was previously thought that the key to determining the harmony of two-color combinations was the hue, it has recently been assumed that the difference in lightness and saturation have a fairly dominant influence. Furthermore, by excluding the hue of the reference color and processing it, it becomes possible to express the relationship between colors located in the three-dimensional space of hue, brightness, and saturation on a two-dimensional plane, and This is because the number can be reduced as much as possible.

When the degree of harmony is expressed on a transparent plate, if the degree of harmony is expressed as a number, it may be possible to display the number at a position corresponding to each color indication on the Munsell color chart. However, it is usually sufficient to rank the degree of harmony into "good harmony region,""intermediate harmony region," and "disharmonious region," and display the boundaries between them.

(Function of the invention) According to this invention, when selecting a two-color combination that harmonizes with one arbitrary color, the degree of harmony between the arbitrary one color and another reference color whose brightness and saturation match is displayed. By superimposing a transparent plate on Munsell's color chart, it is possible to easily understand which range of colors the above-mentioned arbitrary color is likely to harmonize with.

Examples of this invention will be described below with reference to the drawings.

(Example) An indication 2 of the degree of harmony of an arbitrary reference color (for example, N-5, hereinafter the colors are based on the Munsell display) with each color of an arbitrary hue plane (for example, 5R) is displayed on a transparent plate 1. and Munsell's color chart (5R hue plane)
3 is combined. The display 2 of the degree of harmony is as follows:
It is composed of the letter "G" indicating a "good harmonic region", the letter "N" indicating an "intermediate harmonic region", the letter "B" indicating an "inharmonic region", and the boundary lines of each region.

Using the transparent plate 1 and color chart 3 shown above, it is possible to know the degree of harmony between the color of brightness 5 and each color on the 5R hue plane. Therefore, the color scheme selection tool of this invention can also be realized by a combination of one transparent plate and one color chart. However, in practice, it is preferable to combine the following types of color charts and transparent plates.

Color chart 10 hue planes (5R, 5YR, 5Y, 5GY, 5G, 5BG,
5B, 5PB, 5P, 5RP) Brightness 2.5, 7.5, 10
All color charts of.

Transparent plate A predetermined chroma (for example, 1, 2, 3, 4, 6,
Displays the degree of harmony with each of the 10 hue planes (8, 10, 12, 14).

In this example, the required number of transparent plates is 78 if made using the colors shown in Munsell's color chart.

Next, we will explain how to use the color scheme selection tool of this invention.

One color used in the two-color formulation is N-5,
When selecting a color to be combined with this, first consider which hue surface color to combine this with. If it is decided to combine the colors with those of the 5R hue plane, the transparent plate 1 displaying the degree of harmony of N-5 may be placed on top of the color chart 3 representing each color of the 5R hue plane. Through this operation, it can be understood that there is a high probability that a passable combination of two colors will be obtained by selecting a color in the area displayed as "good harmonic region G" or "intermediate harmonic region N".

In the above, if one color is N-2, then N
The transparent plate 1 shown in FIG. 3, which shows the degree of harmony with each color of -2, is used.

Next, if one color used in a two-color combination is e.g.
If it is 5G6/8 and the other color is the color of the 4B hue plane, the transparent plate in Figure 4, which represents the harmony of brightness 6 and saturation 8, is the color representing each color of the 4B hue plane. Layer it on the chart. It can be understood that colors included in the "good harmony range" harmonize well with 5G6/8.

(Effect of the invention) According to this invention, there is a transparent plate that displays the harmoniousness of the color combination of an arbitrary standard color displayed on the Munsell color chart in correspondence with the Munsell color chart, and a Munsell color chart. Since the color scheme selection tool is constructed by combining the color chart, by overlaying the transparent plate on the color chart, it is possible to grasp the quality of the harmony in the two-color combination. In addition, since the quality of harmony is shown as an area corresponding to the color chart, the number of transparent plates can be reduced as much as possible, and the suitability of the combination of colors not shown in Munsell's color chart can also be understood. can do.
