Engine bay paint

I know the engine bay should be painted to match the body color.

I just picked up this car and the engine bay is sprayed T5, Copper Poly, right now. I got the car because my son wanted it (didn’t hurt that I wanted it too), but he really wants to paint it turquoise for the final color, Q4 or Q5, and the car is originally a turquoise colored car I believe. (All original inner panels are turquoise color)…

So my question - Do I respray the engine bay and engine bay seam to fender before bolting up the fenders? Or can I leave it painted this color and it won’t cause a problem? Besides it may drive me crazy knowing I left it lol…
