对于颜色视觉，人眼必须区分光谱上不同的能量分布。这通常被视为波长域中的问题，类似于根据图像中的空间位置来处理空间分辨率。本文试图用系统对光谱能量分布的响应来处理色觉，光谱能量分布是波长的正弦函数。这些被称为梳状滤波光谱，其处理类似于空间正弦曲线方面的空间视觉。这让我们对三色性的原因、油滴的优点以及红色和绿色机制的狭窄分离有了一些了解。光敏颜料的吸收光谱是波长的四次方根的函数，可以叠加。
For color vision, the [human] eye must discriminate different distributions of energy over the spectrum. This is usually treated as a problem in the wavelength domain, analogous to treating spatial resolution in terms of spatial positions in the image. A treatment of color vision in terms of the system''s responses to spectral energy distributions that are sinusoidal functions of wavelength is attempted. These are called comb-filtered spectra, and the treatment is analogous to that of spatial vision in terms of spatial sinusoids. This gives some insight into the reasons for trichromacy, the advantages of oil droplets, and the narrow separation of the red and green mechanisms. The absorption spectra of photosensitive pigments are superimposable if plotted as a function of the 4th root of wavelenth.
