Sadly not all the colors were taken in picture I think. I am sure there is a green one in Japan but never seen a damn pic.. and the fact I only save high-res, makes I don't have any white Enzo pics, but there are at least a couple around..
Anyway, what I have here is:
Rosso corsa
Rosso corsa with yellow touches:
Rosso Scuderia (actually in the metal it looks less orange than this, but it gives a good idea)
Nero
Giallo Modena
Blu Pozzi ( I think)
Grigio Nurburgring?
Grigio Titanio
