What is chromaticity?

  • (noun): The quality of a color as determined by its dominant wavelength.
    Synonyms: hue


Chromaticity is an objective specification of the quality of a color regardless of its luminance, that is, as determined by its hue and colorfulness (or saturation, chroma, intensity, or excitation purity).
