Subject: BS: COLORED Shadow? From: Ebbie Date: 06 May 10 - 11:34 AM I realize that I ask really dumb questions and here's another. Now, we all know that the reason that shadows are not in color is that, unlike reflections, the light is blocked, . But last night I came upon a puzzler. I went by a car parked in a lot. This car was white and on one side it had broad GREEN stripes. I thought at first that it must have been painted that way and then I saw that it was the same pattern as the fence railing alongside. The sidewalk (pavement) is upslope there as is the railing.) There was a streetlight which hit the railing. I stuck my hand up into the light so that my hand's shadow was outlined on the car. My hand shadow was GREEN. I walked around and checked the various shadows that that streetlight was casting- all of them were black, devoid of color, as was my own. So. Was there something in the car's paint that created this phenomenon? |
