Saturation, sometimes called chroma, is the strength or purity of the color.
Saturation represents the amount of gray in proportion to the hue, measured as a percentage from 0% (gray) to 100% (fully saturated). On the standard color wheel, saturation increases from the center to the edge. The
Saturation effect lets you adjust the saturation of the entire image.
In the Properties Window change the effect properties. The only property available for setting is Saturation Level.
