    Sorry for the confusion. Yellow is a single wavelength of light. We perceive it with the green and red receptors in our eyes, but it is a single wavelength. Purple isn’t a single wavelength, but two that are being interpreted as a color.

    That was the distinction I was calling out.

      and that is why i didn’t say the same explanation, but similar

      both, in my opinion, suffer from the clickbait disease “YOU CAN’T SEE YELLOW 😱” (directly, because to see it you use two light receptors combined) “PURPLE DOESN’T EXIST 😱” (as a single wavelength colour because as opposed to the other colours of the rainbow it uses a combination of red and blue wavelengths)

      i don’t blame you for either of course, i’m just expressing my general annoyance with the phrasing of both science facts
