AP PSYCHOLOGY

Detailed explanation-1: -The color constancy explanation of the dress phenomenon is partially supported by the recent finding that the illumination inferred by observers in the photograph is negatively correlated with their dress color matches (yellower illumination implies bluer dress match and vice versa; Witzel, Racey, & O’Regan, 2017).

Detailed explanation-2: -The retinex theory of color vision explains color constancy by postulating the existence of three retinexes or image systems, associated with the three types of cones that are compared to obtain sophisticated information.

Detailed explanation-3: -Remember, the dress is actually blue and black, though most people saw it as white and gold, at least at first. My research showed that if you assumed the dress was in a shadow, you were much more likely to see it as white and gold. Why? Because shadows overrepresent blue light.
