In this paper, we present a modification method of indistinguishable colors on the basis of the Color2Gray algorithm for people with color vision deficiency (CVD). Compared with people with normal color vision, people with CVD have difficulty in distinguishing between certain combinations of colors. To address this problem, we modify saturation and lightness components of the original image to preserve visual detail when perceived by people with CVD. The proposed method can automatically construct a transformation to maintain details for people with CVD while preserving naturalness for normal viewers. In addition, high-speed processing of recoloring is achieved by clustering on the basis of color quantization using the median cut algorithm.
