heal.abstract	In this article, a tetrachromatic colorimetric model is proposed. Four monochromatic stimuli are used as primaries instead of three to achieve colorimetric matches in mesopic vision. Tetrachromatic colorimetric matches are assumed in such a way so as to hold in both the photopic and the scotopic levels of adaptation. The fourth primary helps to balance the rod contribution in mesopic vision. The proposed model is based on the experimental observations that (a) trichromatic matches can be achieved in any light level and (b) once a tetrachromatic match is made, it holds at all radiances. The main outcome is that (a) only three channels in human vision system are important for color matching at mesopic and photopic levels and (b) additivity can be preserved at all levels once rod input is taken into account.
