对光线的适应几乎立即开始，但需要超过1分钟才能达到稳定状态。在这项研究中，颜色外观的变化与色适应后5分钟开始适应光。使用几种不同的适应场：（1）具有叠加测试的全背景与邻近测试外部的环绕;（2）仅由长波长光组成的均匀适应场与具有由其他色度组成的添加的“上下文”的相同长波长场。测量结果表明，适应10秒后是不是几乎完成，相反，颜色外观继续改变超过2分钟。此外，添加彩色背景下有一个更大的影响颜色外观几分钟后的适应，相比10秒的适应，由于一个较小的整体变化的外观在稳定状态下，上下文存在。© 2000 John Wiley & Sons，Inc.

Adaptation to light begins almost immediately, but requires more than 1 min to reach a steady state. In this study, the change in color appearance with chromatic adaptation is followed for 5 min after the onset of adapting light. Several different adapting fields are used: (1) a full background with a superimposed test vs. a surround outside a contiguous test; (2) a uniform adapting field composed of only long-wavelength light vs. the same long-wavelength field with added “context” composed of other chromaticities. The measurements show that adaptation after 10 s is not nearly complete; instead, color appearance continues to change for more than 2 min. Further, adding chromatic context has a greater effect on color appearance after several minutes of adaptation, compared to 10 s of adaptation, due to a smaller overall change of appearance in the steady state when context is present. © 2000 John Wiley & Sons, Inc.
