— LCD motion blur is a well‐known phenomenon, and a lot of research is attributed to characterize and improve it. Until recently, most studies were focused on explaining the effects visible in black‐and‐white patterns, and hence color effects were ignored. However, when a colored pattern is moving over a colored background, an additional motion‐induced artifact becomes visible, which is referred to as chromatic aberration. To describe this phenomenon, our model to characterize the appearance of moving achromatic patterns is extended in such a way that it now calculates the apparent image from the temporal step response of the individual primary colors. The results of a perception experiment indicate that there is a good correspondence between the apparent image predicted with the model and the actual image perceived during motion.
