UI Materials and RGB

Stat_fire.pnghuh.png

So here’s a blueprint of the material and what the material has to deal with. The fire-like symbol would have an opacity mask to have the lighter part opaque, and the darker part molded into a translucent circle behind it. The opaque color for this symbol doesn’t get corrupted while the circle thing I made (which is supposed to be the same base color as the darker part) gets a few shades lighter.

Of course character customization might not be affected, but I find the problem annoying when I’m trying to make an optimized UI because I want to use the minimum amount of images possible.

So what post processes take place in the UI?
