Research Abstract

Illumination changes cause shift in spectrum of light reflected from object surfaces, while perception of surface colour tends to be constant because of colour constancy. Liquid colour, however, appears different under various chromatic lights. In order to reveal why there is much less effect of colour constancy on liquid colour, we investigated the colour appearance of liquids and object surfaces under various chromatic lights.
