Abstract

Is the response of color vision mechanisms linear and additive for stimuli with different spectral radiant power distributions? We studied this possibility by means of results obtained when differential chromaticity thresholds are determined in metameric conditions for an achromatic stimulus. Colors corresponding to stimuli with smooth spectral radiant power distributions and a wide bandwidth are matched with colors corresponding to stimuli and narrow bandwidth (very different degrees of metamerism).
