Howdy,
I am trying to introduce lighting into an openGL app. The shape that I am trying to light is a box. Some sides have a tecture mapped onto them. Others just have colors defined at the vertices which blend throughout the surface. However when I tenable lighting the colored surface all appear a flat red brown color while the tectured surface look fine. Anyone know what going on? I noticed that when lighting is off, if I call glColor3f with a blue color arguement before I texture a surface only the blue component of the texture appears. But if I do the same thing with lighting on the texture looks normal. Does glColor3f have no effect when lighting is on?

Nope, you need to deal with material properties when lighting is enabled; check out OpenGL Lighting FAQ for some useful info.

Colours work completely diferent when lighting is enabled. Check out...
