[ L. saturatio: cf. F. saturation.] 1. The act of saturating, or the state of being saturating; complete penetration or impregnation. [ 1913 Webster] 2. ( Chem.) The act, process, or result of saturating a substance, or of combining it to its fullest extent. [ 1913 Webster] 3. ( Optics) Freedom from mixture or dilution with white; purity; -- said of colors. [ 1913 Webster] Note: The degree of saturation of a color is its relative purity, or freedom from admixture with white. [ 1913 Webster] 97 Moby Thesaurus words for " saturation": Munsell chroma, Technicolor, amplitude, bellyful, brewing, bright color, brightness, brilliance, chroma, chromatic color, chromaticity, color, color quality, colorfulness, colorimetric quality, congestion, cool color, decoction, drench, drenching, ducking, dunking, engorgement, fill, flood tide, full, fullness, gaiety, glut, gorgeousness, high tide, high water, hue, hyperemia, imbruement, imbuement, impletion, impregnation, infiltration, infusion, injection, instillation, instillment, intensity, interpenetration, leaching, lightness, lixiviation, maceration, marination, more than enough, neutral color, overbrimming, overburden, overcharge, overflow, overfreight, overfullness, overload, overspill, overweight, penetration, percolation, permeation, pervasion, plenitude, plethora, pulping, pure color, purity, repletion, richness, satiation, satiety, satisfaction, saturatedness, saturation point, seething, skinful, snootful, soak, soakage, soaking, sopping, souse, sousing, spring tide, steeping, suffusion, supersaturation, surcharge, surfeit, tint, tone, value, vividness, warm color1. 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.

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.
