Abstract

Most conventional models of suprathreshold color vision¹,² specify that, for neutral adaptation conditions, short-wavelength (S) cones signal blueness and short-wavelength redness, middle-wavelength (M) cones signal greenness and yellowness, and long-wavelength (L) cones signal long-wavelength redness and yellowness. A notable exception is Ingling and Tsou’s model³, in which M cones assist S cones with the blueness signal.
