What color trim with white walls + red accent wall?

I am getting ready to redecorate my room and essentially what I want are white walls with a red accent wall that will eventually have "Keep Calm And Carry On" on it (kind of like an over sized poster, but painted on my wall). I thought about painting all of my trim black because I've never really been a fan of white on white walls/baseboards/casings/etc? Is the black an okay idea or is there another color that would look nice against the red and white?
