The Development of the CIE 2000 Colour-Difference Formula: CIEDE 2000

Researchers developed a new CIE color difference equation based on CIELab that includes lightness, chromaticity, and hue weighting functions; an interactive term between chromaticity and hue differences for improving blue color performance; and a scaling factor for CIELab a* scale for improving gray color performance. The combination of f..
