Niallmoran has a full pre-facelift brochure showing colours, the one I have does not.
From the facelift brochure -
Solid - 130 Alfa Red, 601 Luxor Black
Metallic - 384 Emerald Green, 117 Brunello Red, 739 Moonsand grey, 472 Odyssey Blue, 612 Silver Grey, 632 Metallic Black, 600 Atlantic Grey, 684 Geo Grey
Iridescent - Nuvola Blue
Not as many colours then!
The sticker on bootlid inner left hand side will tell you the code and descriptive name in Italian, although my facelift sticker was wrong - Quotes 600, paintshop recently noted it was actually 684
From my sig pic - The prefacelift is 612, the facelift 684.
Note that in the brochure wee box Nuvola Blue looks nothing like it does in the flesh - Actually looks like Tjeerd's colour!
