I am gathering this bits and pieces
apparently vertices can carry secondary colors. These secondary colors are "added" after the texture stage if and only if the lighting affects are off.
Apparently I read that the lighting effects can cause secondary colors.

This is also being quoted as a multi-texturing pipeline
Optionally, after all the texture units, a second linearly interpolated color (the specular color) can be added in the color sum stage (if supported), followed by application of fog. The shading pipeline just outlined is commonly known as the traditional OpenGL multi-texturing pipeline.
