Paper Abstract

Light filled in a room consists of direct and mutual reflected components. Thus the color of light shifts physically to that of an interior of a room when the interior is colored. However, it is not understand how we interpret this color shift caused by the mutual reflection. In this study, we examined how we interpret the color of light filled in a room by using a light source color matching method. The test box had the chromatic interior and those of the matching box achromatic. The results indicated that subjects perceived the color shift produced by the mutual reflection as belonging to the light source.
