There has been some experimentation with white roofs in the American south and they make a useful contribution to reducing the need for air conditioning. I found several internet sites which discussed this from a search a couple of years ago.
Black asphalt roads are useful in clearing the ice from roads in winter. Some time ago, white painted cars were more vulnerable to rust. I don't know if it is still the case. They provide poor contrast in winter. Something that stands out better is safer.
