Description

[Detailed explanation of the invention] (Field of industrial application) This invention relates to a color selection board for the purpose of easily understanding the quality of two-color combinations, and is widely used in design and other fields that deal with colors. It is something that is used.

(Prior Art) It has been thought that hue is the main element that influences the degree of harmony in two-color combinations. For this reason, there is no known device that shows the degree of harmony of a two-color combination based on hue, which takes brightness into consideration.

(Problems to be solved by the invention) However, in recent years, it has become clear that the degree of harmony in a two-color combination is largely influenced by lightness rather than hue. Based on this fact, there has been a problem in that conventional instruments that take only hue into consideration cannot properly judge the degree of harmony of two-color combinations.

(Means for Solving the Problems) The color selection board of this invention is made up of two plates, at least one of which is transparent, which are superimposed and fixed so as to be rotatable, and the first plate has Munsell's 10 Scale axes corresponding to the hue are provided radially at equal intervals, and the brightness difference is displayed in the radial direction on each scale axis. A reference line in the radial direction for adjusting the position and a boundary line for determining the degree of harmony between the reference color and other colors are displayed in correspondence with the display on the first plate, and the reference line is It is characterized by being configured so that it can be aligned on the scale axis and on an auxiliary line that radially divides the scale axis into ten equal parts.

Theoretically, the brightness difference should be displayed from 0 to 10, but if the brightness difference is 6 or more, it is easy to achieve good harmony with all hues, so in practice, it should be displayed from 0 to 5.
Or it is sufficient to display up to 6.

(Function of the invention) In this invention, in order to select a color to be combined, it is sufficient to match the reference line represented on the second plate to the hue display of the reference color on the first plate. After doing this, if the range with good harmony displayed on the second plate corresponds to the display on the first plate and the lightness difference of the color to be selected in each hue is read,
Colors that harmonize easily with standard colors can be easily identified.

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

(Example) As shown in Fig. 1, ten scale axes 3 are displayed radially at equal intervals on the first plate 1 with the mounting hole 2 as the center. As a display of the difference, scales 4 of 1 to 5 are displayed at equal intervals (it is said that a brightness difference of 6 or more always provides good harmony). Further, the scale axes are of equal length,
Each end of them has 10 Munsell hues (10R,
10YR, 10Y, 10GY, 10G, 10BG, 10B, 10PB,
10P, 10PR) display 5 is shown.

Next, as shown in FIG. 2, a reference line 8 is displayed on the second plate 6 in the radial direction from the mounting hole 7, and the hue and brightness displayed on the first plate 1 are Corresponding to the difference display, the degree of harmony between the standard color and other colors is displayed. 9 in FIG. 3 is a boundary line between good and bad, region G is a region where it is relatively easy to obtain good harmony, region N is an intermediate region, and region B is a region where it is relatively easy to obtain disharmony.

Next, FIG. 3 shows the third plate 11, and the first
Auxiliary lines 10 (11 lines) in the radial direction are displayed, which radially divide the space between the two adjacent scale axes 3, 3 of the plate into 10 equal parts.

The color selection tool of this embodiment connects the three transparent plates (the bottom layer may be opaque) to the metal fittings through the mounting holes 2, 7, and 12, as shown in FIG.
3, they are configured to be superimposed and fixed so as to be rotatable. 14 in the figure is a knob.

Next, how to use the color selection tool of this invention will be explained.

When the standard color is 10R5/8.

In this case, first, the reference line 8 of the second plate 6 is overlapped with the 10R scale axis of the first plate 1 (FIG. 4).
After that, by reading the display on the first plate according to the boundary line 9 of the second plate, the range of colors that are easy to harmonize can be grasped. According to FIG. 4, the following can be understood.

In the hue range of 5RP to 10R to 5Y, it is easy to obtain a relatively good harmony by selecting a color with a brightness difference of 3.5 or more (for example, 10YR9), and in the hue range of 5Y to 10GB to 5RP, if you select a color with a brightness difference of 4.5 or more. It is easy to achieve good harmony.

In the hue range 5RP~10R~5Y, the brightness difference is 1.5
If you select the following colors (for example 5R4), it is difficult to obtain a good harmony, and the hue 5Y ~ 10GB ~ 5RP
If you select a color with a brightness difference of 2 or less (for example, 5B4) in the range of , it is difficult to obtain good harmony.

If the hue of the standard color is 3G, align the auxiliary line 10 of the third plate between the displayed 10GY and 10G of the first plate, and then press the third auxiliary line counting from the scale axis of 10GY. Align the reference line 8 with 10a (Fig. 4),
The colors to be combined can be selected in the same manner as in case (1) above.

In addition, although the third plate was incorporated in the above embodiment,
The third plate is not an essential requirement, and instead of the auxiliary line 10 on the third plate, an auxiliary line with fine scales should be displayed along the circumference between the scale axes 3 and 3 on the first plate. You can also do it.

(Effect of the invention) According to this invention, scale axes corresponding to Munsell's 10 hues are provided radially at equal intervals, and each scale axis has a
The plate that displays the brightness difference in the radial direction, the reference line for matching the standard color, and the plate that displays the boundary line of the degree of harmony with other colors are fixed and overlapped so that they can rotate freely. By rotating, it is possible to grasp the extent of the harmony between any standard color of the Munsell system and other colors based on the two elements of hue and brightness difference. The reference colors can be set in 10 levels of lightness and the reference lines can be aligned, making it possible to accurately judge whether the harmony is good or bad, and also to grasp and consider a large number of color schemes based on actual conditions.
