Hello. I'm working on a 2D program with OpenGL and I'm looking for a way to mask individual bits of colors. Something like glColorMask() but with float arguments instead of booleans, if that makes any sense.
To be more specific, I want the world environment in my program to have a blueish/whitish tone during winter and a slight orange tone during summer.
My program consists of flat square textures layered on top of each other. There are no 3D objects, so the advanced lighting mechanisms of OpenGL would be a little overkill.
Thanks in advance!
