Color and brightness constancies depend reciprocally on saturation.

Color and brightness constancies may not be independent, since increasing a sample saturation should decrease the demand on the color constancy and increase that on the brightness constancy [Color Res. Appl.43, 630 (2018)CREADU0361-231710.1002/col.22227]. We tested this claim using color and brightness constancy data from Foster et al. [Vis. Res.41, 285 (2001)VISRAM0042-698910.1016/S0042-6989(00)00239-X], whose observers made side-by-side and successive comparisons of central patches ("asymmetric matches") presented in pairs of identical Mondrian displays with simulated illuminants of 25000 K and 6700 K daylights. Saturations (CIE "chroma") of the central patches varied from 0.007 to 0.092. For most observers (as in a toy Gaussian model of the surface reflectance spectra), increasing saturation reduced color constancy and increased brightness constancy.

颜色和亮度的一致性取决于饱和度。

颜色和亮度的一致性可能不是独立的,因为增加样品饱和度会降低对颜色恒定性的要求,而增加对亮度恒定性的要求。Appl.43,630(2018)CREADU0361-231710.1002 / col.22227]。我们使用来自Foster等人的颜色和亮度恒定性数据测试了此要求。[可见 Res.41,285(2001)VISRAM0042-698910.1016 / S0042-6989(00)00239-X],其观察者并排比较并连续比较了成对的Mondrian显示器中的中央补丁(“非对称匹配”)具有25000 K和6700 K日光的模拟光源。中央补丁的饱和度(CIE“色度”)从0.007到0.092不等。对于大多数观察者(如表面反射光谱的玩具高斯模型),
