I like Laser blue or silver. Looks like yellow is not a choice, but the price is right! (I paid $750 over for my loaded yellow P5) My brother in law has a midnight blue one and I don't really like it. Silver really shows off the lines of the car, and laser is nice and bright, but I have always liked bright cars.
As for which will look good with a tint, I think silver, then laser. Dark blue cars don't look right tinted IMHO.
