APPROACH TO COLOR APPEARANCE BY COLOR VISION DEFICIENT OBSERVERS
It is difficult for color vision defective (CVD) to discriminate some of color combinations, be- cause of the lack of one or two types of cones. As known as color universal design, it is fortu- nately not so difficult to measure abilities of color discrimination on CVD and to work out countermeasures. It is the difficult and fundamental problem, however, to estimate color ap- pearance on CVD. Because we do almost have no method to describe the color appearance directly at this moment, we have to use color names (or other descriptive words) to explain the color appearance. However, we cannot confirm that one color name means the same percep- tion on each observer. Thus, in this paper, we tried one limited approach to investigate the color appearance on CVD, by color naming method in comparison with the data on color normal observers with color vision deficiency simulation glasses.
