Title: COLOR SELECTION COLOR CHART, COLOR SELECTION COLOR CHART-GENERATING METHOD, AND COLOR SELECTION COLOR CHART-GENERATING PROGRAM
Abstract:
The purpose of the present invention is to provide a color selection color chart in which color patches are efficiently disposed. Provided is a color selection color chart in which multiple color patches, including a first color patch, a second color patch and a third color patch disposed in order, are formed and which satisfies the following conditions (a) and/or (b). (a) The absolute value of the lightness difference between the first color patch and the second color patch in a first scale in which lightness is perceptually more even than lightness in the CIE L*a*b* color system and the absolute value of the lightness difference between the second color patch and the third color patch in the first scale are equal. (b) The absolute value of the chroma difference between the first color patch and the second color patch in a second scale in which chroma is perceptually more even than chroma in the CIE L*a*b* color system and the absolute value of the chroma difference between the second color patch and the third color patch in the second scale are equal.
