I can't believe Jaguartvr is talking total bollocks!
Stripes just introduce additional turbulence - everyone knows it's down to paint colour and black cars are always fastest!
Black is faster by keeping the air near the surface warmer, it reduces the viscosity of the air in the boundary layer. This reduces drag, like shaving your legs (oh come on - we all do it - don't we?).
This was confirmed to me by professor Pat Pending of the ACME Black Paint Company (the bit about air viscosity not leg shaving)
