1. <graphics> In colour theory, the "colourfulness" of a stimulus relative to its brightness, the amount of the dominant wavelength relative to other wavelengths in the colour, one of the three coordinates in the {hue, saturation, value} (HSV) and hue, saturation, brightness (HSB) {colour models}. White, black and grey contain equal amounts of red, green and blue light and are completely unsaturated. A pure colour with very little gray in it is highly saturated. The amount of saturation does not affect the hue of a colour and is unrelated to the value (total amount of light in a colour). There are several competing mathematical definitions of saturation. saturation">http://www.ncsu.edu/scivis/lessons/colormodels/color_models2.html#saturation. saturation/saturation.html">http://www.pomona.edu/academics/courserelated/classprojects/visual-lit/saturation/saturation.html. 2. The state of any system that is operating at its maximum capacity, e.g. a network connection that is carry a continuous stream of data with no idle time. Capacity planning aims to monitor load and increase resources before saturation is reached. (2008-05-09)
