This work continues previous research by the same authors [J. Opt. Soc. Am. A 23, 2077 (2006)], where empirical small–medium color differences were represented by an ellipsoidal equation EGP in the Uniform Color System of the Optical Society of America. Now logarithmic compressions on chroma and lightness are introduced to produce a new space with Euclidean color-difference formulas EE. The CIEDE2000, EGP, and EE formulas are found statistically equivalent in the prediction of many available empirical datasets. However, EE is the simplest formula providing relationships with visual processing. These analyses hold true for CIE 1964 Supplementary Standard Observer and D65 illuminant.
