From the color order system of Albert Munsell to the hairy details of CIEDE2000, color science has long addressed perceptual differences between colors in the spatial domain. In this presentation, we focus instead on the temporal domain, studying the perceived rate of change of gradually-changing LED lighting. We can intuitively describe the rate of change, or speed, of a color transition in CIELAB Delta-E per second; however, such a measure is not perceptually uniform. We conducted an experiment in which we compared the perceived rate of change between dynamic color transitions in chroma and hue directions, and between hue changes in centered at the five principle Munsell hues. Results of the experiment are expressed in terms of ratios of speeds in CIELAB Delta-E per second that represent points of subjective equality between transitions centered at different base colors and in the hue and chroma directions.
