This silver car has four doors and an aerodynamic shape with a spoiler on the back. It's parked on a road with trees in the background. The car has four black tyres that stand out against the gleaming silver paint. To bring out the shape of the car, I would use a lighter shade of silver on the hood, trunk and spoiler, with a slightly darker shade on the four doors to make them pop. In the background, I could use a blend of greens and browns to make the trees pop. Then sweep in a light misty blue or grey to provide a backdrop to the trees and roads. For the finishing touches, maybe add two or three white strips across the body of the car and a few white streaks of light here and there.
