You’re right about our perception but the color spectrum is based on wavelengths and doesn’t represent color mixing. It only does that when you make a circle out of it and then you see purple between blue and red and that’s your standard RGB color wheel.
Colored lights do mix. It’s called an additive color since you are adding different lights to create a new color. So red and blue light does Infact create purple light and to get green you have to mix red and yellow light. Mixing RGB or CMY creates white this way.
The other is subtractive color mixing, like when we paint, to get green we mix blue and yellow instead. Mixing CMY, RYB or RGB would give you black.
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.

Explain. I’m too high to understand this.

Fine do you want to call it a violet onion then? They are basically the exact same damn thing and violet is a wavelength

Thanks for the TIL

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.

No need to be such an asshole about it. Keep that on reddit.

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.
