An abridged color‐appearance model named CIECAT94LAB is proposed in the present study. It consists of the CIE 1994 chromatic‐adaptation transform with some improvements and the CIELAB formula. CIECAT94LAB is easy in computation and can predict almost all the color‐appearance phenomena. It was tested using the experiments conducted by CSAJ, Breneman, and McCann et al . In addition, a new measure is proposed for comparing the predictability among various color‐appearance models. The measure is independent of the scale in each of the color‐appearance models. © 1999 John Wiley & Sons, Inc. Col Res Appl, 24, 422–438, 1999
