Crispening is the phenomenon whereby the color differences between two stimuli are perceptually larger when viewed on a background that is similar to the stimuli. The phenomenon is discussed and simulated based on a color constancy model called Maximum Color Separation (MCS). The simulation results have shown the same results with the generally known results related to the crispening phenomenon.
