Figure 1 The dependence of colour on context: simultaneous chromatic contrast. The central square is physically the same on the two halves of the figure, but differs in colour appearance because of the surrounding context.

Figure 2 The colour constancy explanation for #thedress. The image formed on the retina by the dress photograph might, in the actual scene, have arisen from a dress consisting of blue and black material under warm illumination (left) or of white and gold material under cool illumination (right). The colour constancy explanation for the different perceptions of the dress suggests that cues to the illumination in the dress image are unusually ambiguous, and lead to different people unconsciously correcting for different illuminations, in turn evoking different colour percepts.
