We investigate immanent dichromaticity in trichromatic observers by using MDS (Multidimensional‐Scaling). The results show that color‐constellations yielded when observing R‐G neutral‐ and Y‐B only changed‐stimuli provides strong evidence of concave‐shaped dichromic. The results of additional paired comparison tests on subjective saliency reveal that the second coordinate of MDS reflects perceived chromatic saliency.
