I'm buying a new car and I've been told to avoid black or white cars because dirt shows up on them so easily. Do you have any opinions on that?
user
Yes, I can tell you what I know, and then if you have any questions I can try to clarify.

Sure, tell me what you know. Does dirt really show up easily on white cars?
user
Yes, I’ve heard that it does.  Some people have also told me that it’s pretty much a universal fact that black cars get dirty quickly, because black is more reflective than white or gray.

Well yes, generally I would agree with that.  In fact, there is something specific I can say: if you look at the dirt on a white car, it will be obvious whether it came from the road, or was otherwise deposited by rain, snow, or other natural phenomenon.
