Luminance
Colors
Color Luminance calculates the relative luminance of an input color. For correct result, the input must be in the Linear color profile, which may be a bug[1].
This should not be confused with the "luminance" output of nodes such as Color To HSL, which produce different results.
Inputs
Color (Color)
The color to calculate the relative luminance of.
Outputs
* (Float)
The relative luminance of the input color.
