Color intensity refers to how bright or dull a color looks, according to Art Studio Chalkboard. This term is most often used in art and photography but can also have other applications. Bright colors are considered more pure, while dull colors can appear indistinguishable or gray.
Saturation, chroma and chromacity are used to describe color intensity in art. While the precise meaning of each word may be interpreted differently, they are often used interchangeably when describing color intensity. For example, chroma is considered to refer to the brightness of a color when it is compared to the brightness of another color that appears white.
