Hi All,
Was reading a popular women's magazine a while back and came across this little blurb at the bottom of one of the pages. It states:
CHOOSE BLUE! Color studies have shown that when we see blue, our body temperature instantly goes down. Swiss researchers theorize it's because our temperature and pulse are regulated by light-sensitive proteins in the retina of the eye. Stay-cool bonus! Wearing a blue shirt boosts sunburn protection by a whopping 544%; ultraviolet rays actually "bounce" off the color blue, so they can't penetrate your skin!
Does anyone know if there is anything to this claim? Thanks Mary Jackson

Mary, I tried putting a variety of the significant words from this into Google, and came up with nothing whatsoever. I can't help feeling if there was anything in it, someone somewhere on the internet would have something to say

This is beyond my ken. It is true that if something appears blue then it is reflecting, rather than absorbing blue light. And blue is closer to the ultraviolet spectrum than is say, yellow or red. So it is possible that a blue fabric may have some spill-over reflectivity in the violet and ultraviolet but there is no good reason a priori to think so. By way of example, snow is very, very black (absorptive) in the infrared. So you can't be sure about extra-visible absorbtion or reflection from what we sense in the visible.
However I like the color blue.
