Universe Pale Turquoise, On Average

utter rubbish
Or perhaps it could be because turquoise is abundant in the south west and stands out against the brown and red rock of the desert. Humans love rare, shiny things and turquoise was the SW tribes' version of gold.
The website you're linking to says that it is correct to claim that the color of the Sun is green because the Sun's peak wavelength is in the green part of the visible spectrum.
Bullshit.
Start with any light whose energy is broad on the spectrum, add a low energy but very narrowly focused spike of green, and these guys would call the color "green" because of a single spike on a spectrogram. Color perception is computed by an integral of intensity over wavelength, not by looking at the highest intensity peek.
Please stop trying to be interesting by repeating misleading nonsense that is only true when distorting the most technical jargon.
Bullshit.

To nit-pick, because it's 1:30am and I'm bored:
The sun's emission spectrum is a blackbody curve. Most of its light emission is near the high-frequency end of this curve. Thus, if the peak is in the green range, most of the rest of its light emission will be *near* that range.
While I agree that the sun doesn't look green ("yellow-white" was the term used by the FAQ referred to previously), to say that the argument is completely misleading is silly. This isn't a little, narrow spike - it's a great big wide peak at the crest of a quickly rising curve.
And on that note, I'm going to bed.
Only on slashdot can one read a flamewar between intelligent people on what color the sun is.
What color is the sun in YOUR world?
