Luminance Factors

Specifies the amount that each channel contributes to the desaturated color. This is what controls that green is brighter than red which is brighter than blue when desaturated.

Fraction

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