HSL filter


Based on the human perception of color, the HSL model describes three fundamental characteristics of color:
 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 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 as a percentage from 0% (gray) to 100% (fully saturated). On the standard color wheel, saturation increases from the center to the edge.
 
 Lightness is the relative brightness or darkness of the color, usually measured as a percentage from 0% (black) to 100% (white).

The Filter HSL allows you to change the colour of the picture with the other colour base, using  hue, saturation and lightness parameters. Changing saturation turns your picture more colourful. Change of  the lightness gives the more realistic effect than the change of the brightness.
