Colorfulness, chroma and saturation are attributes of perceived color relating to chromatic intensity. As defined formally by the International Commission on Illumination (CIE) they respectively describe three different aspects of chromatic intensity, but the terms are often used loosely and interchangeably in contexts where these aspects are ...
Chromaticity consists of two independent parameters, often specified as hue (h) and colorfulness (s), where the latter is alternatively called saturation, chroma, intensity, [1] or excitation purity. [2] [3] This number of parameters follows from trichromacy of vision of most humans, which is assumed by most models in color science.
The basic challenge for any color appearance model is that human color perception does not work in terms of XYZ tristimulus values, but in terms of appearance parameters (hue, lightness, brightness, chroma, colorfulness and saturation). So any color appearance model needs to provide transformations (which factor in viewing conditions) from the ...
Colorfulness is the degree of difference between a color and gray. Chroma is the colorfulness relative to the brightness of another color that appears white under similar viewing conditions. This allows for the fact that a surface of a given chroma displays increasing colorfulness as the level of illumination increases.
The Hunt effect or Luminance-on-colorfulness effect [1] comprises an increase in colorfulness of a color with increasing luminance. The effect was first described by RWG Hunt in 1952. [ 2 ]
Some tints and shades of blue. In color theory, a tint is a mixture of a color with white, which increases lightness, while a shade is a mixture with black, which increases darkness.

The saturation intent is designed to present eye-catching business graphics by preserving the saturation (colorfulness). It is most useful in charts and diagrams, where there is a discrete palette of colors that the designer wants saturated to make them intense, but where specific hue is less important.
