It is said that utilizing red as an indicator of emphasis and so on is not very effective because red looks very dark with protan, one type of color-blindness. However, such color’s psychological effects, generally called “color’s representations” or “color’s codes,” are as effective as perceptual aspects from the point of conveying information, so designers want to use these effects for individuals especially with normal color vision in many cases. In this paper, we examined to what degree the color's effects (visibility, saliency, significance and danger) were maintained, and what colors would be effective to use, when we need to modify colors so that color-blind individuals are able to differentiate the colors from the viewpoint of color design considering various color vision characteristics. |
