Math and Code behind Hue-Saturation Tool - heavy_duty - 05-01-2019
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.) Saturation Factor if enhancement in saturation (say 40%)
d.) But..what is primary color?
The math behind this would be really helpful. If someone can shed some thoughts on this it would be helpful.
