– Does the color black absorb only light, or does it absorb heat as well?

So, for example: if I wore a black undershirt beneath a long sleeved shirt or jacket, would I be warmer than if I wore a white shirt? I know that you can “see” heat with infrared goggles, but are infrared light and heat basically the same thing?

Heat can be radiated as black body radiation, that is infra red radiation and therefore photons aka light, juts a lower wavelength.

But regula heat transfer is done by molecules bumping into each other.

So the suns light is black body radiation, just super intense. And it heats your shirt, but a black shirt will reflect less light so it will absorb more heat.

But heat and infra red is not allways the same.
