Mesh borders

[Ozz]

Hey Guys!
I need help here. I build a 3D blueprint sketch program for robots. Here an example:


Now, all mesh parts (spheres, tubes, cones) have to have a thick white border and colors inside. Is it possible to do this with material scripts? Or any other ideas? My main problem is to set the color of the borders and bodies... in that picture above I used only ambient and diffuse

My first thought is to look at a glow shader. otherwise im not sure...

Shader is probably best but you could also try two UV sets and assign different materials.
