According to the trichromatic theory of the human color vision, color perception is based on the excitation of three types of photosensitive receptors on the retina of the human eye, called cones, differing in spectral sensitivity. The problem of finding cone sensitivities, generaly considered as an experimental task, has been investigated as the problem of receiving and processing the signal and solved mathematically. The theoretical solution is based on analysis of the color space from some rationalistic point of view. Although any rationalistic approach to such complicated system as human eye should be viewed with some skepticism, cone sensitivities derived theoretically agree closely with spectral sensitivity curves constructed from numerous experimental data for normal and dichromatic color vision. The good agreement with known solutions shows that rationalistic approach may be applied to human eye. We consider the last conclusion as the most interesting result of our work.
