TL;DR: The plausibility of this model to explain subjective colors is demonstrated quantitatively by inferring impulsc 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.
Abstract: Subjective colors such as those generated by Bcnham's Disk, are illusory colors perceived with certain temporally modulated achromatic signals. We propose a model to explain subjective colors which is based on physiologically reasonable temporal differences between color channels within the retina. We demonstrate the plausibility of this theory quantitatively by inferring impulsc 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.
