Yeah, I think the white and black mix is okay. It's a matter of personal taste of course. The various Pentax color offerings have been the subject of many discussion threads here, some in ridicule, some in serious debate.
For a while it looked as if the pink K-r also came with a pink lens, although I'm not sure if those were just stock photos based on the Japanese market offerings. I was thinking to leverage this to get my wife to join the club, but pink was just too much, even for her. And then I would have gotten stuck carrying it around.
