Hi,
hmm, I dont know how to make this with the OpenGL Api, but lets say your
Texture is in an BMP file. You could just parse the file and change the
colors before you create your Texture. You could even create a knew file, so
that you will just need to open the new file, once you changed the colors.
Cu,
