Hue / Saturation / Luminance
The Hue / Saturation / Luminance filter allows you to adjust the hue, saturation, and luminance of a specific color component in an image or simultaneously adjust all the colors in an image.

Hue is the color reflected from or transmitted through an object. It is measured as a location on the standard color wheel, expressed as a degree between 0° and 360°. In this case the hue is a hue shift, expressed as a degree between -180° and 180°. In common use, hue is identified by the name of the color such as red, orange, or green.

Saturation, sometimes called chroma, is the strength or purity of the color. Saturation represents the amount of gray in proportion to the hue, measured from -1 (gray) to 1 (fully saturated). On the standard color wheel, saturation increases from the center to the edge.
