It tackles on the HUD (heads up display) which is based on this tutorial

I wanted to set the "Text" in color BLACK, but it is more complicated than what I thought.
Setting it to some other color other than black "glColor4f(0.0, 0.0, 0.0, 1.0);" is just fine.
I assume that the culprit must be in the Blending function "glBlendFunc (GL_ONE, GL_ONE);"
I experimented a lot of combinations with no luck. Has anyone experimented on this one on top of textured 3D in the backgrounds working?
