What Color is Your Universe?

Astronomers have worked out the color of the Universe � and the calculated shade lies between aquamarine and a pale turquoise. Note that this does not describe any particular star or dust cloud or planet in any particular quadrant of the Universe. It happens that the large number of old red giant stars and hot new blue stars averages out to a frequency just on the green side of turquoise.

Does this "mean" our "universe is turquoise"? For practical purposes, it means very little. For theoretical purposes, it means that if you had an eye large enough to see large swaths of the universe, you might get the impression of turquoise. As so often seems to happen, science makes one statement and the popular press turns it into a whole different message.
