Effects of an interior color on perceived color of lighting in the room

experiment using model box

Abstract

Colors of the inner surfaces of a room must have significant effects on our perception of color of lighting in the room. The aim of this study is to examine how we perceive the color of lighting in a colored room. Two small model rooms (test box and matching box) were used for the experiments. The task of the subjects was to adjust the color of the illuminant of the matching box so that the matching box appeared to be illuminated by the same illuminant of the test-box. It was shown that the subject's judgment of the color of lighting was effected by the saturation of the interior color.
