Abstract: Recently, many researchers have proposed space brightness indices that are well matched to human perception. However, those indices do not accurately reflect space brightness in some cases. Particularly, several studies found that observers reported enhancement of space brightness when there were colored objects (e.g., colored furniture), but the color effects are not taken into account in those indices. In the present study, to examine quantitatively the influence of color on the space brightness, we measured border luminance of color appearance mode for spaces with chromatic or achromatic furniture. Participants observed a test stimulus located in a scale model simulating a room and adjusted its luminance to determine the transition point from object color mode to light source color mode. The results showed higher border luminance in the chromatic furniture condition than in the achromatic furniture condition. This suggests that subject's space brightness was enhanced by chromatic furniture.
