White bike owner here with brown accents, it's a Specalized Expedition and my other bike is cream colored with black accents. I never thought I would pick a white bike but I really like it and also keep it fairly clean. Since I keep it waxed it wipes down easily enough unless I've spent a lot of time on wet/muddy dirt roads, then it needs the hose. I get a lot of comments on my bike about people loving how it looks.

I too kind of like how it looks with a little mud splashed on it, but don't leave it on long
