Paper Abstract

The present study investigates the tendency of individuals to categorize colors. Humans recognize colors by categorizing them using specific color names, such as red, blue, and yellow. When an individual with a certain type of color vision observes an object, they categorize its color using a particular color name and assume that other people will perceive the color in an identical manner. However, there are some variations in human color vision as a result of differences in photoreceptors in the eye, including red and green confusion. Thus, another person with a different type of color vision may categorize a color using a completely different name. To address this issue, we attempted to determine the differences in the ranges of color that people with different types of color vision observe. This is an important step towards achieving Color Universal Design, a visual communication method that is viewer-friendly irrespective of color vision type. Herein, we report on a systematic comparison among individuals with trichromat (C-type), protan (P-type) and deutan (D-type) color vision. This paper is a follow-up to SPIE-IS & T / Vol. 7528 752805-1.
