Saturation and Color Kill
2:0 4
Saturation; 100 = 100%. Scales linearly with value.
5:3 2
Color kill gain. Determines rate of gain decrease above threshold. If pixel value is above
threshold the difference is multiplied by 2^ value-1 (for 0 factor is “0”) and subtracted from
the base gain.
8:6 6
Color kill threshold. Color kill effects only pixels with value larger then 128*value.
