Depends on the Porsche... a longhood 911 would be Tangerine Orange, an 80's Carrera or Turbo would be Silver, 964s look best in black as it hides the ugly rubber seals on the rockers and the late model watercooled 911s look best (to me) in silver or red. A 924 or 944 has to be Guards Red and 928s look properly classy in silver or black whereas a 914 has to be coloured like a jelly bean, Signal Orange or Olympic Blue gets the nod for those cars.
The Cayenne should be clear so I don't have to look at it.
