It's well-established in physics that black or dark-colored objects radiate heat faster and more effectively than light-colored objects.

So, in almost every building that uses steam heat, why are the radiators painted silver or some other very light color?

Dark objects radiate heat better, but they also absorb it better. This would be bad in a radiatior, so it's painted white to reflect light and heat.
I don't know how to post a solution, so I can't put this there.
