text: what color is the universe? of the light, on average. please don't say black. it's a kind of beige.  i'm not kidding.  a few bored astronomers worked up a program to figure it out a couple years ago--i also remember reading that they made a mistake with the first calculations, had to re-do and came up with a different color.  i think beige was the final outcome.  added:  here's a link to the story i was thinking of:  http://www.space.com/scienceastronomy/universe_color_020308.html
