We can remember and recognize visual scenes that we already met. How then, exactly can we recognize colors of those scenes? To answerthis question, we performed an experiment that consisted of two stages; a memory stage and a recognition stage. In the memory stage, subjects memorized 20 pictures successively. In the following recognition stage, the subjects observed 40 pictures and judge, by forced choice method, if each picture was the same as that memorized. Those 40 pictures consisted of (a)ten pictures memorized, (b)another ten pictures changed either their chromatic or luminance contrast of the memorized pictures and (c)the other twenty pictures never presented before. Subjects tended to idetify a picture changed to higher chromatic contrast with the picture memorized. Our result suggested that we can color the image uniquely toward more saturated colors than those actually memorized.
