I was typing a reply to this as I saw Mark's post come through.
In other words, if you want a Corsa, you can have it in any color you want, as long as it's black. You could, of course, buy the bike, take off all the parts, have a powdercoating place work their magic, and reassemble the bike. Or maybe do the powdercoating stuff before the bike is assembled at your LBS.
