If you could pick *any* colour for a car... what would it be?

Ok, so my plan of 'I won't buy a new car this year, instead I'll spend the money on my older Newbie' hasn't quite worked out.... I sorta put a deposit on an Audi S1 tonight :D

As part of the order I have specified 'Custom Paint' - which enables me to pick literally any colour I would like.... so, my first world problem is that now I have to decide!

So the car will look like this:





And at the moment I'm swaying towards Porsche Riviera Blue:


Which I have found on an S1, and it looks fab :D



What would you get?
