    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.

    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.
