Abstract: The paper presents the design features of color sensors made on the basis of hydrogenated amorphous silicon films with the spectral sensitivity of the human eye, their characteristics depending on the wavelength of the radiation of the heated body, varying from temperature, and the dependence of the output voltage of the color sensor on the color of the body under consideration.

Keywords: the color sensor, the wavelength of the radiation of the heated body, the dependence of the output voltage of the color sensor on the color of the body in question.
