Color - Additional Terms

Additional Terms

  • Colorfulness, chroma, purity, or saturation: how "intense" or "concentrated" a color is.

These terms, and others related to light and color are internationally agreed upon and published in the CIE Lighting Vocabulary. More readily available texts on colorimetry also define and explain these terms.
