Learn how to do this in GLSL with OpenGL. Related posts:

This means that if you pass the texture id to the shader, you can replicate all the texturing done in OpenGL. Related posts:

This tutorial will show you how to get and use the material information on your lit objects.

Now we are going to learn how to do per pixel lighting, achieving a more realistic lighting effect.

This tutorial will teach you how to use this information to perform per-vertex lighting, identical to that in standard OpenGL.

But OpenGL can pass your colors to GLSL for you to use.

HLSL does this upon compilation inside XNA, but we have to wait until out shader compiles, which happens at run time.

It allows us to manipulate the scene on a per vertex and per fragment basis, giving us total control.
