Maybe not more, but different wavelengths.
The Wikipedia page does say "The purpose of the colour was to reflect some of the thermal radiation from a nuclear explosion", as far as my experience goes polished metal can still get extremely hot.
- m463 5y agowouldn't it just be different directions? A mirror would reflect light directionally, but white paint would seem to be diffuse. Or said in another way, seeing a laser in a mirror might cause retinal damage, but on a white wall you would just see a dot. (although probably a speckly coherent dot)
- legulere 5y agoThe felt sensation of temperature depends not only on the temperature but also on thermal conductivity. With a low conductivity you feel less of a temperature difference to your body temperature. Most stuff in your apartment should have the same temperature, go and touch some metal objects and ceramic tiles or so.

- hashkb 5y agoI swear when I was a kid the rules must have been different. Every metal slide was always hot enough to fry bacon.
