1. A method for maintaining a perceived hue constancy of a color vector in a display system, the method comprising: fitting an approximation to a perceived hue curve, wherein the fitting the approximation to the perceived hue curve comprises: selecting a number and location of perceived hue curves; specifying a set of curve fitting parameters for each perceived hue curve; and computing an approximation for each perceived hue curve based on a respective set of curve fitting parameters; warping the color vector by adjusting a hue component of the color vector based on the approximation to the perceived hue curve; and displaying image data associated with the color vector.
