I think I'm misunderstanding why some bags/quilts have light
outsides and dark insides. I know it's for radiation, but here's
where I'm confused.
Light colors radiate heat and dark colors absorb heat. So wouldn't
you put the light color on the inside to radiate the heat back at
your body? And the dark color on the outside to absorb ambient heat
into the bag, keeping you warmer?
If the inside is dark, then the bag is absorbing and storing your
body heat rather than letting your body use it. And the light outer
layer is reflecting ambient heat back into the atmosphere instead of
storing it in your bag.
So which is right?
