I've heard people saying that there is an Enzo in "Rosso Dino", which is an orange colour, but from all the pictures I have seen it looks more like a lighter "Rosso Scuderia" red (lighter than Rosso Corase of course) than "Rosso Dino". Also the Enzo register -
http://www.enzoregister.barchetta.cc/ - claims there is one "Rosso Dino" Enzo, but as I've said, I'm yet to see definitive photographs of one.
