Engine painting and alternative colors

I have had a few Mopars with the engine bay done in black. In cases like this I do the engine in body colour...it makes it really stand out. When the engine bay is body colour, then I do the block factory colour but accent the Mopar Performance valve covers like others have done here.
The second pic, the car is all black with a sublime strobe stripe on the side..so the green matched the stripe.
