ABSTRACT
To solve this problem, a special technique for studying color vision was used. The subject has several categories for the names of the colors-yellow, blue, green, red, bright, dark. Subjects can use any of them in a particular order. Each place in this order is weighted, and from these weighted values the vector of color names was constructed. Each color was characterized by a different contributions of color names. Thus, each color was characterized by a specific vector derived from these color names. From these vectors, the subjective differences between the colors were obtained indirectly. The Euclidean distances between the color name vectors were measured, and these distances between the color name vectors were regarded as equivalent to the subjective evaluation of color differences in order to construct a matrix of subjective differences between colors.
