Abstract
Chromatic valence functions for the red-green and blue-yellow opponent-response systems of normal and anomalous trichromats were measured psychophysically using the Jameson and Hurvich hue cancellation technique. Four protanomalous and two deuteranomalous observers with varying degrees of color discrimination loss, and two color-normal observers, served in the experiment. The color-normal data were in good agreement with the results reported by Jameson and Hurvich. Protanomalous and deuteranomalous observers differed with respect to the relative strengths of the two chromatic opponent systems: decreased red-green strength was correlated with poorer color discrimination. Theoretical fits to the opponent-response data were calculated by assuming linear combinations of cone inputs for both chromatic systems and different sets of photopigments for the three classes of observer.
