Colorfulness, chroma, pure color and saturation are related but distinct concepts in colorimetry and color theory, referring to the perceived intensity of a specific color. Colorfulness is the visual sensation according to which the perceived color of an area appears to be more or less chromatic. Chroma is the colorfulness relative to the brightness of a similarly illuminated area that appears to be white or highly transmitting. Therefore, chroma should not be confused with colorfulness. Saturation is the colorfulness of a color relative to its own brightness. Though the general concept is intuitive, terms such as chroma, saturation, purity, and intensity are often used without great precision, and even when well-defined depend greatly on the specific color model in use.
