Although the demonstration of trichromacy failure appeared robust, the attribution of the failure to rod contributions was generally not acceptable, as rods were believed to not contribute to visual processing at photopic light levels.
In addition to the admittedly possibly obscure but substantial error the authors' made in their statistical analysis, they have also made a number of claims based on what appears to be some serious confusion about trichromacy and "prime color" theory.
Our article was designed to be consistent with Thornton's conceptualization of trichromacy and his prime color theory.
Trichromacy, while imperfect at explaining all visual phenomena, explains a great deal of visual phenomena in applied lighting.
The main finding is that trichromacy confers an advantage when selecting ripe fruits from those at various stages of maturity.
FOOD FIGHT Dominy doesn't reject the notion that trichromacy can help primates find some fruits that ripen to a reddish or yellow hue.
Under these conditions, trichromacy and the opponent colors model suggest that luminance will predict brightness perception, at least within the region near the blackbody locus.
Measures that are unconnected to trichromacy and the opponent-colors model, such as CCT, the S/P ratio, [P.
occurs as a result of unequal intragenic recombination that produces hybrid genes (Figure 8b and 8c).
