Years ago (about 1986) I saw a great film on color perception from the perspective of the (controversial) retinex theory of Edwin Land. It had a truly stunning scene in which one is shown one of Land's "Mondrian" displays, and attention is drawn to a green square within it. Then a mask is dropped into the projector so that all but this one square is blocked from view, and we see that in isolation it appears pink, and that the original apparent green color was created by the influence of the colors surrounding it. Whatever one thinks of retinex (and most perceptionists despise it), it is a fabulous demonstration of the maleability of color perception in the "real" world (as opposed to in splendid Helmholtzian laboratory isolation) and can generate a good class discussion of how the phenomenon came to be. Unfortunately, I do not recall the name of hte film and have never seen it again. Does anyone else know?
