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.
But most of the energy in the universe is NOT from the CMB. Remember the Stefan-Boltzmann law: energy per unit area goes like sigma T^4. 3 K is barely a blimp. The billions of stars in each of the billions of galaxies are at 1500 K or more (the sun is 5800 K, blue stars are hotter still). That T^4 comes in like a demon and means that most of the energy we perceive does NOT come from the CMB.
Of course now I've gone and offended astronomers (no intent to. I just find it odd how many of these "discoveries" are treated as if they change life as we know it: As if realizing something alters the past).
