"I think the sky is blue because it's a shift from black through purple to blue, and it has to do with where the light is. You know, the farther we get into darkness, and there's a shifting of color of light into the blueness, and I think as you go farther and farther away from the reflected light we have from the sun or the light that's bouncing off this earth, uh, the darker it gets ... I think if you look at the color scale, you start at black, move it through purple, move it on out, it's the shifting of color. We mentioned before about the stars singing, and that's one of the effects of the shifting of colors."Pat Robertson, The 700 Club
