The Hue filter lets you adjust the hue of an entire image. Hue is the color reflected from or transmitted through an object. It is measured as a location on the standard color wheel. A positive value indicates clockwise rotation, a negative value counter-clockwise rotation. Values range from -180 to +180.

The Saturation filter, sometimes called chroma, deals with the strength or purity of a color. Saturation represents the amount of gray in proportion to the hue. Values range from -100 (percentage of desaturation, duller colors) to +100 (percentage of saturation increase). On the standard color wheel, saturation increases from the center to the edge. The Saturation filter lets you adjust the saturation of the entire image.
