ABSTRACT

The purpose of this paper is to suggest the analysis methodology of map color scheme for the color vision impaired in the objective and quantitative ways. We tried to help solving problems related in using uneven color space and gamut indicated in existing studies. Consequently, we suggested the color-difference measurement method using CIELAB color system for the uniform color space and sRGB color gamut for setting the standard color space. Also, we set minimum color-difference standards for the color vision impaired to prevent misunderstanding color schemes on maps. We analyzed the variation of minimum color-difference before and after the simulation of color vision impairment and recommended safe color schemes for them. The proposed color-difference measurement method with the simulation tool of color vision impairment developed in our previous study can contribute to the recommendation of map color schemes depending on the characteristics of each color vision deficiencies.
