A set of five color difference formulas, cdf-G*, one for each of five regions of the CIE1931 chromatic diagram, is proposed and compared with the CIELUV, CIELAB, and LABNHU formulas. The cdf-G* formulas fit more closely several sets of color difference data. They are useful for color difference applications.
