Answer 1

My guess would be painted, only because you don't want the copper reflecting the rays. You want a color that will absorb the energy, so wouldn't black be best?

Answer 2

if you mean which absorbs heat, it would depend on the colour of the paint. black paint would absorb heat better than white

Answer 3

Bet on Black.

Answer 4

painted black.
