Colorimetry is the science that studies the measurement of colors and develops methods for the quantification of color perception. The hue is the pure state of color: red, yellow, blue … The saturation of a color is its degree of purity. A color is more saturated the lower its content of grays or whites. The colors of nature are always more or less saturated. The intensity, or brightness of a color, is the characteristic that makes it appear clearer, regardless of its saturation.
