My sympathies to you Huyduchoang - finding your NSX bent in a parking lot is a nightmare - I've always said total it but please don't just bend it !!!
IMO putting on a factory painted quarter panel would be the way to go.
Berlina black looks to me like it is just Pitch black which is what the paint store uses to start the formulation any of the variations of black that manufacturers use ( many black cars are just Pitch black ). If Berlina black is indeed Pitch black the odds are very good that the match between panels from various cars will be undetectable. I've had good luck with this on other cars, but I've never tried it with NSX panels. In the best possible world the small amount of paint knocked off the bolt heads would be the only evidence of anything being done to the car at all.
In a less perfect world you would have to paint the panel, but at least you would be painting a panel the doesn't have metal that has been stretched and then put back into shape and maybe even filled with a plastic filler. In my experience thin coats of quality paint put on top of factory paint ( with no filler ) lasts a long time even in relatively hot climates where the metal does a lot of expanding and contracting and the UV is intense.
