A comparison of the CIE 1976 colour spaces

Abstract

Abstract The CIE 1976 colour spaces, CIELUV and CIELAB, have been compared by recalculating the results of a number of reported sets of experimental data. These include the results of just‐noticeable‐difference observations, colour difference scaling, colour matching ellipses, and acceptability ellipses. As a means of representing the colour difference data uniformly, it is shown that neither colour space is significantly better than the other. Attention is drawn to some anomalies in the CIELAB space.
