Alistair, if you are looking for an early car (S1) many were ordered in dark blues (Ferrari Tour de France Blue, BMW LeMans Blue, Porsche Midnight Blue, etc); there is also a high proportion of silver tones (some with blue tint, others moving toward gunmetal).
From S2 forward, first owners seem to have become braver and therefore, there are a myriad of colours to choose from.
Good luck in your search.
