Universe Pale Turquoise, On Average

    Our sun is actually pale green in color. So that's yet another thing that makes us average.

      I looked again, and, durn it, it's yellowish.

      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.

      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.

    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.

    Well, given that the colors are indeed given as normed values, essentially all they give us is a hue and a saturation, no luminosity. Assuming a full luminosity (highest given # is is equal to FF), it easily computes to:
    RED:0xB1
    GREEN:0xFF
    BLUE:0xE1
    I used the WinXP Powertoys calculator...and actually, it gives decimals...err....well, it puts a . into hex numbers and gives you what probably amounts to 1/16, 1/256, etc. places after it....just in case anyone's interested.

      This means that the HTML encoding (e.g,. in "bgcolor") is "#B1FFE1" - script kiddie biff'.

      My God, this means that the universe is someone's middle-school science faire project... and God himself is said student.

      It explains so much!....

  6. Isn't it obvious, really? by PhilHibbs · · Score: 3, Interesting

    They're talking about the visible spectrum, which is a slice out of a much broader range of frequencies. If you take an arbitrary slice out of an evenly distributed set of data, you would expect the average to be right in the middle, which is roughly where turquoise lies, so surely this is statistical nonsense.
