Abstract

A new group of color-difference formulas is proposed that gives better results than the previous formulas supplied by Romero et al. [Appl. Opt. 28, 4697–4702 (1989)]. The new formulas are deduced from chromatic discrimination data and behave more consistently at the boundaries between regions of similar hue in the CIE-1931 diagram. They also fit well with experimental color-difference data.
