What color should I paint these cars?

If you're trying to establish a "look" for a team, consistent across different race events, I would steer you to something simple. As a fan, what I gravitate towards are the teams I know before the graphics come up

KingJester: Green & Black, Bolo Brown: Green & Gold, Dog Squab Racing: Blue & Gold, Milestone Diecast: Green & Orange

Give me a photo with 100 cars in it, and I know those guys' builds right away, and that's using two colours. Simple and direct. You can go to three colours, like R-Lo Racing, but don't feel like it's a requirement to be "cool" in the scene

If you like your high school or university sports team colours, give that a go! Just have fun in the process

I will use differnt ways and remove the tempos

and re-decal them if I like their colors

as Chris said some chose colors to run with

I am a bit more random but lean towards blue metalic

Last time I did a Camaro I painted it like a cop car.
