Title: Corona Color Correct - Formula behind it?
Post by: Nate101 on 2020-01-10, 11:28:56

I've been working with the colorCorrect tool and am trying to understand the math going on when I adjust hue, saturation and brightness.  For example, I have a purple input color:

CoronaColor HSV = (190, 255, 84)

And I want use colorCorrect to increase the brightness by 0.5.  Is there a formula to calculate the resulting output color in HSV (a brighter purple)?

Appreciate the help.

Hey all, just wanted to bump this to the top again and see if anyone can help.  Really just want to understand the formula that drives the colorCorrect brightness adjustments.

Appreciate the help.

I agree that contrast works kind of strange.
