Abstract
A neural mechanism is studied in which three primary receptors interact in such a manner that only a small region is in activity for a given colored stimulus. The similarity to the color triangle is noted. The introduction of an additional primary receptor may or may not change the dimensionality of sensation space in this mechanism. Problems of discrimination of color, absolute judgment of saturation, and hue are discussed.
