description: Apply hue-dependent color adjustments using lookup curves.
Hue and saturation are computed from the the source RGB values. Depending on the hue value, the various adjustment values are computed, and then applied:
sat: saturation gain. This modification is applied last.
lum: luminance gain
red: red gain
green: green gain
blue: blue gain
r_sup: red suppression. If r > min(g,b), r = min(g,b) + r_sup * (r-min(g,b))
g_sup: green suppression
b_sup: blue suppression
sat_thrsh: if source saturation is below this value, do not apply the lum, red, green, blue gains. Above this value, apply gain progressively.
The 'Luminance Mix' parameter may be used to restore partially or fully the original luminance (luminance is computed using the 'Luminance Math' parameter).
