Color/Saturation
 
 

Saturation is the purity of a color. Grayscale images feature no color, their saturation is 0. Use this function to change the colors' saturation.

Setting the Bias parameter to a positive number will increase the saturation. A value of 100 quaranties the maximum possible color purity.

Negative values decrease the texture's saturation, while -100 produces a grayscale image.
