Colour constancy of liquid materials under various chromatic illuminations

光照的变化会引起物体表面反射光谱的偏移，而由于颜色的恒常性，对表面颜色的感知趋于恒定。然而，液体的颜色在不同的色光下显得不同。为了揭示为什么颜色恒常性对液体颜色的影响小得多，我们研究了不同色光下液体和物体表面的颜色外观。

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.
