REFINEMENT OF THE RLAB COLOR SPACE

The prediction of color appearance using the RLAB color space has been tested for a variety of viewing conditions and stimulus types. These tests have shown that RLAB performs well for complex stimuli and not-s o-well for simple stimuli. This article reviews the various psychophys ical results, interprets their differences, and describes evolutionary enhancements to the RLAB model that simplify it and improve its perfo rmance.
