Abstract

A model is proposed to explain subjective colors which is based on physiologically reasonable temporal differences between color channels within the retina. The plausibility of this theory is demonstrated quantitatively by inferring impulse response functions from physiological and psychophysical data and using these functions to predict the output of the different color mechanisms to temporally modulated achromatic signals which produce the sensation of color. This constitutes an essential nonlinearity in the transformation of visual stimuli in which spatial, temporal, and chromatic information interact. Such nonlinearities account for the cell responses and should be considered in the design of visual media where temporally modulated signals are presented to take into account alterations in the perception of color.
