I recently heard Bill Nye speak and he spoke about a phenomenon that I had
never noticed and have not been able to reproduce. He said that when you
are outside and cast a shadow that the shadow will have a blue hue to it
because of the color of the sky. He pointed out that it is really only
noticeable when the shadow is projected onto a white surface. He said to
go
outside in a white t-shirt and hold your arm at an angle so that it casts
a
shadow on the shirt and it will have a blue hue.
I have tried this and cannot see the blue.
I understand the theory behind why this would be true . . . but I have not
been able to reproduce the effect. Has anybody else been able to? Maybe
it's the southern California smog making the shadows have a reddish-brown
hue instead of blue (LOL)?
