I noticed this when I was holding a piece of paper in front of my blue led computer light. when a object (finger) is placed in front of the paper wiht the blue led light shining on it the shadow of the object is yellow. why?
I tried to explain it as yellow is the complementary colour of blue so yellow appears if blue is absorbed but why is it absorbed in the region of the shadow?
