        Is it a skittles reference or is it a reference to purple not being an actual color and thus not a part of the rainbow?

            Purple, the color directly between red and blue, is a creation of your mind interpreting a band of light that triggers your red and blue sensing nerves, but no green is sensed. The actual band of light we can see goes from red to green to blue. Purple doesn’t fall between those colors, meaning it wouldn’t be included in a rainbow, and isn’t any “pure” light you could see, since it doesn’t fall on the spectrum.

            Essentially, any time you see purple, you’re seeing two different frequencies of light that your mind interprets as a single frequency.

              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

              Would this not disqualify any mixed color? We only have receptors for three colors, and if we’re arguing that purple isn’t a color because it’s actually two mixed together, that should also mean colors like orange, yellow, cyan, magenta, atc are also not colors by that definition right?

              Your definition of color is based only on human perception? Is purple a color for a mantis shrimp?

              Edit: I guess not in a pure sense because it’s still two wavelengths of light. Perhaps a mantis shrimp can detect a totally different wavelength and sees it as “purple” or something.

              Now I’m thinking about how we don’t know how other humans interpret colors. Like what I see as red, you may see as blue. Ugh.

                Definition I’m using is any color that can be expressed as a single wavelength of light. Purple cannot be, since it’s actually two wavelengths simultaneously.

                  Perceiving it as a color seems more practical though. It’s not like we look at “red” and think “ah yes, a single wavelength of light”

    This feels like a case where botanical science should just have picked a different name. If you invalidate everything people think of as a berry and then tell them a dozen things that are clearly not berries are, in fact, berries, you’re just making the word berry meaningless.

    Berry means a tiny, usually sweet, fruit-like growth from a plant. The kind that is usually picked in bunches. The kind that you use to make smoothies. That’s a berry.

    Botany did us all a disservice by choosing the word “berry” to mean “a specific thing which invalidates everything you think is a berry.” Just call that plant structure something in Latin, ffs.

      Well, cooking terms and botany terms are not the same. Any non reproductive part of a plant is vegetable. But in cooking we have a completely different idea of what vegetables are.

      This really doesn’t matter because most people are not botanists and those who are probably know the terms. The only people that care are quirky internet people with debates about weather or not potato salad should be considered a cake or something.

    TIL, wow. I mean, to be fair, “berry” is in the damn name, so I never questioned it.
