Red + blue(indigo) = a color not on the chart? but in between the two colors is clearly green!
We perceive purple as an activation of Red and Blue cones in our eyes… The color itself actually doesn’t exist as a discrete wavelength and is a collective hallucination of sorts.
Violet and Purple are indeed not the same thing. Purple exists in that we perceive it… that’s not what I’m arguing against. It’s just that it’s not a “real” color. It’s only because of this “mass hallucination” of sorts that we’re okay just accepting that it must be a color when it isn’t representable as a single spectrum color like every other color. It is purple… but purple isn’t a real color, it’s effectively just shorthand for saying that this color is both blue and red. It’s just you being human.
Brown has the same problem in that it’s just dark orange (from the light spectrum perspective). It turns out that brightness context matters to us, so we choose brown to represent a large swath of that.
Just because violet light triggers both red and blue receptors in our eyes, that doesn’t mean there is only discrete red and blue light hitting them. It’s just that light with 380nm to 450nm wavelength triggers both typed of receptors. So there is violet light.
Just look at the spectrum chart here. https://www.thoughtco.com/the-visible-light-spectrum-2699036
Red + green = yellow…
Green + blue = cyan…
Red + Yellow = Orange…

Edit: Also… Brown isn’t a color. https://www.youtube.com/watch?v=wh4aWZRtTwU (whoops, wrong link originally, fixed now.)
Fine do you want to call it a violet onion then? They are basically the exact same damn thing and violet is a wavelength

I have a shorthand for “only real in the context that it’s real for humans”… hint, it has four letters and starts with “real”.
:) interesting info!

violet IS a discrete wavelength. Purple is not.
