Purple

It’s just a lighter shade of purple. In modern color theory, which is used in computer screens and printers, there are 6 main colors. Red, green, blue—and their opposites cyan, magenta, and yellow. Everything else is a combination of those. And if you combine them with white or black, you can control how light or dark they are.
There are many different single pigment reds, in paints.
There are many different single pigment blues, in paints.
Red and blue make purple, they can also make violet.
By adding quite a bit of water to a purple watercolor, you can easily make violet; however, you can NOT make violet into say a DIOXAZINE PURPLE. But....you certainly CAN make a violet shade ( by adding lots of water ) to a dioxazine purple!
OTOH...you can NOT make a COBALT VIOLET out of any old purple.

“Inside a color band are many different shades and violet IS a shade of PURPLE!”
Violet has its own part of the visible spectrum. Purple is a not part of that spectrum. It also has to have frequencies of red mixed in.
“...there is no color ON THE SPECTRUM that’s created by combining long- and short-wavelength cones.”
Purple is not a Spectral Color. Spectral Colors are single frequency/wavelength. Mixing different frequencies produces colors that are not in the spectrum, just like mixing different frequencies of sound produces melodious tones or screeches like fingernails on a chalkboard........

Can we just be happy that Purple exists as the lovely mystery (or not) that it is?
Violet is NOT a "color" per se; it is a SHADE of a color we call PURPLE.
Red, blue and yellow are "PRIMARY COLORS" and every single other "color" is a mix of those, and/or water content.
Oils, pastels, gouache, and dyes are the same, but sans the water.
But..........NO, magenta is only ONE shade that red and blue makes.
Magenta is far more red based ( with pink overtones ) than purple is. Magenta is a tertiary color.
“Nonsense.”
I’ll go one better - Balderdash!
People only exist in our minds. Yeah, sure. When we’re not looking at them, they don’t exist. They don’t affect the world at all.

That was your problem. You still get an F.
Again, you may know pigments but you know nothing about how the eye and brain process light.

Go learn some color theory. :-)
But DO allow ME to have mine.
And the picture of the color spectrum, used in the article, is PURPLE! Violet is a different shade. And this isn't a case of "a color by a different name" is that color.

Go watch some color mixing tutorials and learn something.
What’s a woman?
“And the picture of the color spectrum, used in the article, is PURPLE! Violet is a different shade.”
Violet is not a “shade” it has its own spectrum.
Purple is created by adding two parts of the visible spectrum.
Some people are colorblind, which, according to this article, means that their brains don't work right. Yes?
