Color Ideas?

Spotted this handsome half moon and had to have him. His color is unusual for what i normally see. Was wondering if anyone had any thoughts as to what he might be considered? The photo makes him look more blue than he is but he's very iradescent and purplish.0813131313a (800x600).jpg

I would probably call that some kind of copper because of the green/blue coating in the bright light. Hes really pretty whatever he is called!
