Dr. Mitsuo Ikeda Research This laboratory tries to prove that the chromatic adaptation is determined by adaptation to the color of illumination and not by adaptation to the colored objects. In other words the color appearance is determined by the brain and not by the retina. In order to prove this hypothesis experiments in this laboratory do not employ 2D displays but always actual rooms which are 3D spaces. Keywords: space perception, illumination, chromatic adaptation, recognized visual space of illumination. 2D vs 3D.
