[All] Which member do you think looks good with black hair?

I like him a lot, but that's partly because he's my favorite (lol), but I think Mark looks better with black hair than I thought! He looks a bit like a pretty boy and a rebel lol. Do you know what I mean? Mark's charm is revealed in a new way when his black hair is added to his slightly exotic name, and I really like that. lol I wonder what other Season 4 members think. Who do you think looks good with black hair?
