Hood Scoop Paint color - on inside of scoop?

Funny....I never really paid attention to this until now....

I have a fiberglass hood with a six-pack scoop. This hood uses the stock hinges with the springs disconnected. (This was all done by the PO.) The car is red so the engine bay is (freshly) painted red as well. The underside of the hood is red. The topside/exterior of the hood is red but will soon be painted flat black as it was intended to be. So once painted, I will have a flat black hood but viewing it from the front of the car, seems to me that the red on the inside of the scoop (which is really part of the underside of the hood) would show.

What do people do...leave the underside of the hood body color as intended or do you paint the underside of the scoop black or ???? Curious how others have this on their car.
