Fraction

Specifies the amount of desaturation to apply to the input. Percent can range from 0.0 (fully desaturated) to 1.0 (full original color, no desaturation).

Programmers: Define desaturated color D, input color I and luminance factor L. The output will be O = (1-Percent)*(D.dot(I)) + Percent*I
