Abstract
Individual differences in colour perception, as evidenced by the popular debate
of “The Dress” picture, have garnered additional interest with the
popularisation of additional, similar photographs. We investigated which
colorimetric characteristics were responsible for individual differences in
colour perception. All objects of the controversial photographs are composed of
two representative colours, which are low in saturation and are either
complementary to each other or reminiscent of complementary colours. Due to
these colorimetric characteristics, we suggest that one of the two complementary
pixel clusters should be estimated as the illuminant hue depending on assumed
brightness. Thus, people perceive the object's colours as being biased toward
complementarily different colour directions and perceive different pixel
clusters as chromatic and achromatic. Even though the distance between colours
that people perceive differently is small in colour space, people perceive the
object's colour as differently categorized colours in these ambiguous
photographs, thereby causing debate. We suggest that people perceive the
object's colours using different “modes of colour appearance” between
surface-colour and self-luminous modes.
