That's actually not the case with OSG. If you look at the source for osg::Material, you will notice it calls glColor with one of the material colors (depending on the color mode). This means you can use osg::Material to control the color of geometry even when lighting is disabled. If ShapeDrawable did not call glColor, it would be possible to use osg::Material to control the color with lighting disabled. At the very least, I think there should be an option to have ShapeDrawable inherit the color. I don't see anything wrong with having such an option and I'm sure Robert would accept a patch for it.
