Our visual system can adapt to various changes in the color environment and maintain a stable color appearance (e.g., color constancy). The combination of multiple cues presents within objects and surroundings in a natural three-dimensional scene should contribute to color constancy. However, specular highlights would have only a little contribution. Face and skin are essential natural stimuli in our life. It has been suggested the existence of color perception specific to facial skin. We showed that reddish skin appears brighter than yellowish skin for Japanese observers, but our international comparison implies that various factors may also influence facial color perception.
