The article presents the results of an experimental research of color distinguishing by city dwellers of China and a midland of Russia. Comparison of color vision was made under the basic chromatic characteristics (hue and saturation) in terms of spherical model of color distinguishing. The cross-cultural differences are not revealed. That is for about threshold light stimulus, the color distinguishing is carried out in visual system of the people belonging to different cultures, absolutely equally, both for radiation, and for light reflected from a surface. Hence, the spherical model of color vision is adequate representation of color distinguishing without dependence from a cultural habitat of subjects.
