My opinion probably won't be too popular.
When I saw the Camaro in person, I really didn't care for it. And some colors like yellow made it downright repulsive to me. Then I saw one up close in silver. It was stunning and made it look like a completely different car from the others I saw.
The fact that silver is probably the easiest color to keep looking clean and great for not retaining heat is an added bonus. That being said, I think black with the red stripes look pretty good also. However, I was very surprised by how flimsy the decals were when I felt them. I don't think they would last very long.
