    White stuff in a dark space makes it easier to spot when shined upon. And outer space is a pretty fucking dark place.

    I’d use neon lime instead or glow in the dark coating, but it’s expensive or annoying to the eye.

      That is only a side effect. It’s white (or metallic) to reflect as much radiation from the sun as possible, to prevent overheating.
