You're quite right. How could this possibly be worth investigating? There is nothing useful that we could discover here.

  What? Nowhere did I say it wasn't worth investigating. How did you come up with that? I'm complaining about a seemingly non-scientific statement that sounds absurd at first glance. If you want to do rigorous testing of different combinations of wavelengths to see if anything can be distinguished and how that fits into our current frameworks of color interpretation, then great! But saying someone can see twice as many colors of the rainbow sounds like nonsense unless you have a rigorous scientific framework for that, and the article sure doesn't provide one.

    > But it also might not do much of anything at all, if it's then mapped to our existing opponent process [1] that is fundamentally based on red vs. green and blue vs. yellow. In other words, it would just be a redundant or ignored sensory input to our conceptual color processing.

    Everybody has their own BS detector, and mine happened to go off in this case. But you're quite right.
