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.
