Universe Beige, not Turquoise

Researchers at John Hopkins University initially reported it was turquoise, but the software they used contained a flaw that implemented a non-standard white index to arrive at the mint chocolate chip green color." The other color was much nicer than this beige.
Use Plank's constant to find out what the peak wavelength at 3 degrees Kelvin (the cosmic bg temp) is. This is the color of the Universe, as it is the color you "see" in all directions (if your eyes could see this wavelength, that is).

Here's an example of where averages mislead. The interesting thing about color is not the average, but the contrast between colors. Trust me; I'm renovating my house right now. Or trust anybody who's stared too much at the sun.
