I would say that you should not mess with tglColor3* calls.
Except from that and my other comment, LGTM.

I'd prefer to keep the OpenGL and TinyGL renderers as close as possible for things like this, but I can drop the TinyGL changes if you'd prefer.

I have no strong opinion on this.

I think keep them in aligned. that what I do in 3d engines

Merging, then.
