The illusion that is now commonly referred to as 'White's illusion' involves changes in the lightness of the mid-grey test elements that replace sections of the black or white bars of a black-white. One such example is the Munker-White illusion (Munker, 1970; White, 1981), or MW, where two identical gray patches are embedded in a field of alternating black and white bars (Figure 1).
