Immanent dichromatic in color normal observers is investigated by MDS (Multidimensional-Scaling). The results show that (1) color-constellations yielded when observing R-G neutral- and Y-B only changed-stimuli strongly evidence concave-shaped like dichromic, whereas (2) those gained when observing Y-B neutral- and R-G only changed-stimuli evidence oval-shape of saturation-brightness.
