Engine Bay color help

I wanted to paint the engine bay before I take it to get painted, but they dont make the color I want in spray cans. I was going to take all the old stuff off and then primer and paint, but if I cant find the color I want. I will just go black because If I wanted a original car I would keep it Original. I want something that will look good on the outside and something were the motor looks really nice. To put more attention on the motor
