Abstract : An usual visual effect results from moving an 'achromatizing' lens in front of the eye while viewing an intricate multicolored pattern. This consists of a relative change in the spatial position of areas of different color. An explanation of this effect is provided. Secondary visual effects are an illusion of depth, and the production of a border in the absence of one, or the exaggeration and minimization of borders when present. (Author)
