Orange and purple works pretty well for sure. I am not so happy with the rats and I guess I want them more accentuated so it could be an option to make each one. Did I try to do each? One of those get both OK, but this one is the axis. The seats can go red, maybe also call it red then, and this it's probably not looking good. 

Not as bad as you would think. It was a lot of pain to say. Maybe I need to ungroup this and work the colors a little better. That's really worse. Oops. Problematic. I also need to change the light setup. It's pretty much the underwater light, right?
