Tolerance range for skin color variations has been mostly studied in color reproduction of photography and real human faces. As animations have become more popular in recent times, it is important to study the tolerance range for skin colors of character faces in animation images. We recently reported that face shapes influence the skin colors of faces in animation images (Han and Uchikawa, 2016).In the present study, we focused on dependence of the tolerance range on background scenes. In the experiments, the observer estimated skin colors of a character face, which were presented on various backgrounds in a cascade procedure. It was shown that the tolerance range of skin colors was dependent on the background parameters, more specifically, indoor and outdoor scenes, color temperature and level of illuminance in the background. Color constancy index (CI) indicated that effects of color constancy were smaller in animation images than natural ones. Lightness constancy index (LI) was different that depends on color temperature of the background scene. Therefore, tolerance for skin color variations and preferred skin colors in animation images clearly depend on the background.
