Evaluation of the perception of colors by mammals with a view to obtaining a characteristic biomarker of each tested subject takes advantage of the slow pupillary oscillatory response to generate an objective neurological signature of this perception of colors. A method based on pupil frequency tagging is used at a tagging frequency Fadapted to the pupil response speed. A dynamic two-color stimulus is displayed, this stimulus comprising a two-color pattern the colors of which are inverted at the frequency F, one of the colors gradually varying in a range of possible values. From the pupillary response, a signal representative of the oscillation power of the pupil is generated. The minimum of this signal corresponds to the relative iso-luminance of the tested pair of colors.
