Urk is widely known as a nuisance. I think he has some issues. Perhaps he was beaten as a child, I dunno. Just ignore him.
As for the ano, you can either go with a pattern where chrome parts will look very nice, or you could get parts annoed to match.
I think a silver to black, vertical fade with black barrel would look pretty sweet.
Or maybe try and get it red, but so dark that you have to look at in the light to see the hint of red. That works well with blue and green, too.
Or you could go with Hot Pink, if that's your kind of thing
