For a stable visual world, the colours of objects should appear the same under different lights. This property of colour constancy has been assumed to be fundamental to vision, and many experimental attempts have been made to quantify it. I contend here, however, that the usual methods of measurement are either too coarse or concentrate not on colour constancy itself, but on other, complementary aspects of scene perception. Whether colour constancy exists other than in nominal terms remains unclear.
对于一个稳定的视觉世界而言，物体的颜色在不同光照下应呈现相同。颜色恒常性这一特性被认为是视觉的基础，并且已经有许多实验尝试对其进行量化。然而，我在此主张，通常的测量方法要么过于粗略，要么并非专注于颜色恒常性本身，而是集中在场景感知的其他互补方面。颜色恒常性是否实际存在而非仅在名义上存在仍不明确。
