In tooth-shade terminology, the term that describes the SATURATION or intensity of a color is:

Chroma is the saturation, strength, or intensity of a hue. Hue is the basic color family, and value is the lightness or darkness (the most important dimension for shade matching).Other options: Hue = the color family; value = brightness/lightness; translucency is a separate optical property.Key exam takeaway: Hue = color, Chroma = saturation/intensity, Value = lightness; value matters most in shade selection.
