I don't care much about the color of my bikes. But, I would not want a white one. I just don't like white for anything, except an occasional blouse with black pants!
I am notoriously bad about cleaning my bikes. I hate to tell you how bad my carbon bike looks now, after riding continuously for almost 2 years... I've cleaned it like maybe twice. DH does a thorough cleaning and maintenance a couple of times a year and unless I get stuck in rain, that's it.
