Fire hydrants are red here as well. Not underground though. Policemen wear any number of colors on their uniforms. I've seen blue, black, white, and a dark khaki color. It all depends on what kind of cop you're talking about... local, state, county. Cop cars... where to begin... Chevy Caprice, Ford Interceptor, Chevy Camaro, Hummer, and many more I can't think of.
