Color constancy & chromatic induction

Nowadays the effects of the illumination on color perception are more and more studied using computer monitors.  The results show that observers are quite poor in estimating the illumination and color constancy is almost completely absent when scenes are rendered on a computer monitor. Obviously, these virtual scenes ae quite artificial and it is quite clear that there is no 'real' change in illumination but observers are simply staring at a flat screen. In the picture above we tried to study whether observers would be more color constant when we made it more clear that there is a change in illumination. Hopefully observeres would treat these virtual images more as real surfaces illuminated by a lamp.
