Photo Color Enhancement - Hue Saturation - Primary Color
Hello, I have been using GIMP for a long time. However, I am unable to understand the logic behind one operation. If I were to do Color Enhancement (Hue-Saturation), and I select a Primary color (say Red), I see that only certain colors are enhanced. What is the logic behind this? I am aware of the following:
a.) RGB -> HSL
b.) HSL -> RGB
c.) Factor if enhancement in saturation (say 40%)
d.) But..what is primary color?

The math behind this would be really helpful.

I'm sorry but as it says in the forum announcements, this forum has been DEAD for a long time.

The spammers keep trying to take over.

Save yourself from them and go to https://www.gimp-forum.net instead
