I'd stay away from the white; it will blend from a distance.
DSG is a safe route; but again, it blends in.
Orange is obviously a safe choice; but again it mimics the OE paint/striping.
Sonic blue has a black base and will likely go dark against the black at times. Redfire would have a similar effect.
To me, Orange, DSG, Limegreen would be the order of choice though. You could go with a House of Kolors Candy Tangerine (Or similar named orange) and THAT would be different.
Orange look's good but,is just too bright(plus you don't have a H/D).White
doesn't look quite right.Grey,even though it doesn't stand out that much....
is subtle and blends in better IMO.
