Description

[Detailed description of the invention] This invention simultaneously compares the brightness, saturation, and hue of any color within an arbitrarily set range, and determines whether these values are within the arbitrarily set range. This is about a color ruler that allows you to clearly judge what is going on.

Generally, industrial products such as automobiles and household electrical appliances are painted with unique colors by each manufacturer, but even if the same color is applied to the same model, each product has different hues and colors. Usually, there are slight differences in saturation or brightness.

This is because even if the paint is the same color, each manufacturer adjusts its own color by mixing a single color paint with paint of an appropriate color, for example, in order to create its own unique color tone. However, even if the mixing conditions are the same, it is extremely difficult or almost impossible to reproduce exactly the same color in terms of hue, saturation, or lightness when adjusting paint colors by mixing multiple colors of paint. It's almost impossible.

Therefore, the color of the paint readjusted as above is
Generally, if the hue, saturation, or lightness of a reference color is within a suitably set range, it is treated as the same color as the reference color. This handling of colors is not limited to the above-mentioned paints, but also applies to dyes, pigments, and the like.

Therefore, the comparison judgment as to whether or not the original color of the paint that has been readjusted with respect to the original color, that is, the standard color, is the same or within the same range is determined by the subjectivity of the person making the judgment. For example, even if the brightness is within the range of identity of the standard color, the hue may not be within the range of the standard color. The task of determining whether a color is the same in terms of brightness, saturation, and hue as those of a reference color or within a range that is considered to be the same requires skill and is extremely time-consuming.

In view of the above-mentioned points, the present invention makes it possible to express the range of hue, saturation, or lightness of the reference color by using specific colors, thereby making it possible to To provide a color ruler capable of determining at a glance, without requiring skill, whether or not there are elements of colors to be compared within the range of hue, saturation, and brightness that are recognized to be the same. The structure is such that a standard color is placed approximately in the center of a circular or rectangular flat substrate, and the standard color is placed around the placed standard color. Allowable hue, allowable saturation, respectively for the same reference color having different hues, the same reference color having different saturation, and the same reference color having different brightness.
Also, the permissible lightness is arranged radially.

Next, an embodiment of the present invention will be described with reference to the drawings.

1 is a planar rectangular substrate made of a thin plate such as paper, and here it is formed to have a size of about 200 mm on each side. 2 is a reference color with a specific color arranged in an octagonal shape with an outer diameter of about 50 mm approximately in the center of the board 1, and 3 is a comparative color arranged concentrically with the circle of the reference color. In this embodiment, the reference color 2 is placed in the blank space between the reference color 2 and the reference circle 3 within the large-diameter reference.
Colors 4 and 41 with the same color and different hues, colors 5 and 51 with the same color and different saturation as the reference color 2, and colors 5 and 51 with the same color and different color saturation, and colors 5 and 51 with the same color and different color saturation, and colors 5 and 51 with the same color and different color saturation as the reference color 2, and colors 5 and 51 with the same color and different color saturation, and colors 5 and 51 with the same color and different color saturation, and color 5 and 51 that have the same color and different color saturation as the reference color 2, and color 5 and 51 that have the same color as the reference color 2 and have different color saturation, and color 5 and 51 that have the same color as the reference color 2 and differ only in color saturation. Lightness colors 6 and 61 are arranged radially opposite to each other for each color element with respect to the reference color 2. Therefore, colors 4, 41, 5, 51, 6, 6 related to each of these color elements
1 is the allowable hue and saturation of the reference color 2;
and allowable brightness, which constitutes an example of the color ruler of the present invention.

Here, the colors 4 and 41 of the above-mentioned allowable hue are arranged horizontally with the hue of the reference color 2 as the center, the strong color 4 is placed on the right side, and the similarly weak color 41 is placed on the left side to form the allowable hue. At the same time, the colors 6 and 61 with the allowable lightness are vertically arranged with the high lightness color 6 above the reference color 2 and the low color 61 below to form the allowable lightness, and furthermore, the color with the allowable saturation is 5,
51 forms the permissible saturation by placing the highly saturated color 5 at the upper right of the reference color 2 and the similarly low chroma color 51 at the lower left, and the hue, saturation and Since a range that is recognized to be the same color as the reference color in terms of brightness is formed in the same plane with specific colors,
Colors within the range that are recognized to be the same as the reference color 2 can be visually recognized at a glance with respect to the three elements of the reference color.

In the above embodiment, it goes without saying that the allowable values 4, 41, 5, 51, and 6, 61 for each color element of the reference color 2 can be arbitrarily set or changed depending on the specific color of the reference color 2. Allowed colors for each color element may be arranged in a stepwise manner. For example, a color 62 having a brightness different from that in the above example is provided outside the reference circle 3.

Further, in the above embodiment, the reference color 2 is formed by appropriately forming holes 2a in the portions where the specific colors are placed on the substrate 1, and in the portions of the reference color holes 2a,
The object whose hue, saturation, and lightness are actually to be judged, such as paint or painted parts, is used as the reference color for judgment, and this target reference color is arbitrarily set for each color element of the reference color 2. It may be determined whether or not they are within a range that is recognized as the same.

As mentioned above, the color ruler of the present invention divides the range of reference colors that are recognized to be the same, and the same color of the reference color that is within the permissible range of hue, saturation, and lightness of the reference color, centered around the reference color. The reference color or the color to be compared with the reference color is arranged radially so that it can be judged at a glance whether the reference color or the color to be compared with the reference color is within the range of hue, saturation, and lightness allowed for the reference color. Therefore, it is extremely useful as a color ruler for determining the same color.
