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.
In short: Purple doesn’t have it’s own wavelength. Neither does white, black and the entire gray-scale or any mixing of any colour with the gray-scale and probably more. They’re called non spectral colours.
It might be easier to understand when considering other types of waves. At least it is for me. A simple sound can also be described as a wave with a frequency, but if we play two sounds at the same time, we can’t say that the sum of the waves has any specific frequency. The frequencies don’t add up or multiply or mix as average. The combined sound can only be described as the addition of two frequencies.
In musical terms, purple is not a note, but instead a chord or interval. Red and blue can be individual notes, or they can be mixed as intervals. White is noise and black is silence.
Literally does… There’s a number of colors that we perceive that are fictitious. This is well known in color theory. https://grantsonnex.com/why-purple-doesnt-exist/ Don’t believe me? That’s fine. Listen to an actual artist who’s whole job it is to understand colors. There is no “purple” on the light spectrum. And if you’re the type to say violet=purple… then here you go! https://jakubmarian.com/difference-between-violet-and-purple/
If we cannot define a color by a wavelength… then it’s a color we have to define by how it’s perceived. That’s not a “true” or “real” color. That doesn’t mean it doesn’t exist or cannot be perceived, but that it only exists because we perceive it and wouldn’t otherwise.
“Brown” is also the same problem. Brown only exists in the context of light and darkness. You cannot just produce “Brown” light. You can produce vary levels of “Dark” orange… and in the context of a dark or light background you’ll either see it as orange or brown.
Since you don’t know how to read links. here you go specifically broken out of the paragraph for you to click. Or if you need more because you’re “Special”?
Purple isn’t a real color. Red + Blue on the color spectrum is Green.
Explain. I’m too high to understand this.
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…
Red + blue(indigo) = a color not on the chart? but in between the two colors is clearly green!

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.
You ARE the color
You’re the only color I need
Umm…

Yeah, that doesn’t mean it isn’t a “real” color.

Violet is purple.

Do I have to keep going?
No need to be such an asshole about it. Keep that on reddit.
And just like reddit… they could have actually read the post. But they didn’t. So it looks like we’re all redditors here.
Interesting… So they’re two different colors right?
So purple is a color.
I think it’s better to make the distinction between color and light wavelenght instead of just saying purple isn’t real.
