Color Balance Node
The Color Balance node adjusts the color and values of an image.
Inputs
Factor
Controls the amount of influence the node exerts on the output image.
Color
Standard color input.
Properties
Two different correction formulas could be selected.
Lift/Gamma/Gain
Lift
Increases the value of dark colors.
Gamma
Adjusts midtones.
Gain
Adjusts highlights.
Offset/Power/Slope (ASC-CDL)
Offset
Summand. (Adjusts the overall brightness.)
Basis
Additional offset, allows to specify a negative Offset value.
Power
Over-all exponent. (Adjusts the midtones.)
Slope
Multiplier. (Adjusts the highlights.)
Outputs
Color
Standard output image.

The Offset/Power/Slope Formula
out = (i × s + o)p
where:
out: The color graded pixel code value.
i: The input pixel code value (0 to 1) (black to white).
s: Slope (any number 0 or greater, nominal value is 1.0).
o: Offset (any number, the nominal value is 0).
p: Power (any number greater than 0, nominal value is 1.0).
