Properties of three colors: The quantitative representation of color perception difference is based on the difference of three color attributes: lightness, hue and chroma. The lightness difference represents the difference in depth, the hue difference represents the difference in hue (i.e., red or blue), and the chromaticity difference represents the difference in brightness. Color difference asse...
