I do think that painting the grille black would make it blend in a bit more on the front (with the bumper and hood visor)
I painted mine and while it is a pain to remove is easy to paint and easy to touch up. It should be easier for you to remove since you do not have the bars and winch in the way.
When I did mine I just used cheap rust paint but did sand off the stock paint to give it something to bite to.
Just a thought...
