The almost-illuminant-independent achromatic variable zeta [J. Opt. Soc. Am A 11, 1003 (1994)] is supplemented by two achromatic variables, both almost illuminant-independent. The results are numerically verified and obtained by means of so-called (human) visual system-response functions, defined as those linear combinations of the color-matching functions that constitute the best possible approximations to delta functions. It is argued that they and not the cone sensitivities are basic to understanding the visual system as a color-constant signal detection system. The three variables solve the color-constancy problem and define a chromatic adaptation transform for blackbody radiators of temperature T. The generalization of the results to arbitrary well-behaved illuminants is discussed.
几乎与照明无关的消色差变量ζ[《美国光学学会志A》11, 1003 (1994)]由另外两个几乎与照明无关的消色差变量补充。结果通过所谓的（人类）视觉系统响应函数进行数值验证和获得，这些函数被定义为构成对δ函数的最佳近似的颜色匹配函数的线性组合。有人认为，对于将视觉系统理解为颜色恒常信号检测系统而言，它们而非视锥细胞敏感性是基础。这三个变量解决了颜色恒常性问题，并为温度为T的黑体辐射器定义了一个颜色适应变换。讨论了将结果推广到任意表现良好的照明的情况。
