Here is what I learned about ColoringAtributes. It is used when there is no light and no vertex color.
I found error in my normal generation.

You have to make sure that 1. the light has an InfluencingBound, which includes your Shape3D object 2. the light comes from the correct direction (an object lighted from behind appears black) 3. I am not sure, but maybe you have to specify the ColoringAttributes as well, because there the shade model for the object is specified
