I vote for white with clearcoat.
White reflects all of the sun’s energy in the visual range. The darker the color, the more of that energy is absorbed rather than reflected. That energy, and the heat it creates, causes the paint to dry out and oxidize. The less of the energy that’s reflected, the less of that process goes on. The less of that process that goes on, the longer the paint lasts. Clearcoat helps too, since it’s an added layer of protection.
Having said that, any color will look good for many years of it’s kept clean and waxed. That is absolutely the single best thing you can do for a finish, no matter the color.
