      Umm…

      Reflection is just as effective as absorption. As long as the UV isn’t passing through the fabric into you, you are fine.

      Well butter my biscuit, I might be wrong. There are other of factors to take into account, but it makes sense that, the portion of light that does make it through a light fabric will keep on reflecting inside the garment until it is absorbed or escapes back out. Like a photography light box.

        Skincancer.org is my source for darker colors being better protection

        I don’t have the highest degree of confidence in it but it makes sense to me that absorption matters more than reflection because a lot of the reflected UV will be going through the shirt and onto your skin

        That’s why materials like linen aren’t as good for UV protection. They’re light weaves and let a lot of light through, still

        Look at the sun through a white shirt, then black. Which is brighter?

          The white would be as it would absorb (then converted to heat) less light and would reflect it instead.

          Thebottom half is highlighting the absorption by showing radiance (giving off it’s own/stored energy), not reflection.
