ah a similar explanation to why yellow is not an actual colour either

the silly explanation that has no effect on how we perceive, use, or think about colour. sigh why are the people responsible for those studies calling those colours not real? Why not just colours resulting from mixing other colours like the artists have done since the invention of paint?

    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
