The hypothesis that rods contribute to color information has not been generally accepted primarily because of the apparent lack of a connection between the scotopic luminosity function and color-mixture data. We present analyses showing that the scotopic luminosity function is intimately related to color data over the entire spectrum, indicating that rods play a central role in normal color vision. These results, not readily explainable in terms of the trichromatic theory, suggest an alternate idea of sensing in terms of the psychophysical quantities called brightness, hue, and saturation.
视杆细胞对颜色信息有贡献这一假说尚未被普遍接受，主要原因是在暗视觉光度函数与颜色混合数据之间明显缺乏联系。我们的分析表明，暗视觉光度函数在整个光谱范围内都与颜色数据密切相关，这表明视杆细胞在正常颜色视觉中起着核心作用。这些结果难以用三色理论来解释，它们提示了一种基于称为亮度、色调和饱和度的心理物理学量进行感知的替代观点。
