Which color is hottest in the dark?
Which color is hottest in the dark? I am aware that in sunlight a black surface will become hotter than a white one. What about in a dark room? I assume there is always a small amount of heating due to infrared radiation. Which color is the hottest? Flat black? White? Silver? Gold? Which is the coldest? Is there any difference at all between colors, even if it is only a difference of a hundreth of a degree?
(My apologies. I did not mean to ask this in the entertainment section. Now I can not figure out how to move it.)
