色覚異常における色認知メカニズム——色の識別から色の見え方まで——

摘要

The characteristics of color discriminability and color appearance in color deficiency are described based on our psychophysical experiments investigating how the color perception of paper and light were influenced by various factors for anomalous trichromat observers. People with color vision deficiency (protan and dutan) show less discriminability to the combination of reddish-greenish color, but have various categorical color recognition including "red" and “green”. It should be noted that their discriminability and appearance change depending on the combination of those color, size and luminance as well as viewing conditions.
