What Color Engine Bay?

My car is multicolored and unpainted and definitely has what people call a mad Max vibe.. they can see the dual quad sticking out but when I lift the hood you can tell they weren't expecting that....
I think whatever color you choose should be very contrary to what the color on the outside is and have a clean extreme impact.... That way when they look at the car they won't be expecting it...
That’s actually why I painted the engine when I swapped in the 360. I’d debated about just using as much of the ratty parts from the 318 as I could and leaving everything shabby and mismatched to continue the look of the rest of the car but at the advice of members on here, I decided to have the engine bay be something nicer to look at when the hood is popped.
