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.
What is violet at the end of the visible spectrum, then? We call the higher wavelength stuff ultraviolet, and violet looks purple to me, so I’m having trouble reconciling this stuff with what you’re saying.
I appreciate the skittles reference
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?
Colour need not be on the rainbow. Colour is the human experience of colour which includes purple
Our minds don’t care whether a color is pure or whether it is a mix. We see those colors.
Like the berries there are technical definitions of colour that don’t mesh with the common definition
the heck do you mean purple is not an actual colour??

Like binaural beats for the eyes?

Violet is dark spectral blue, added as a separate color by people who wanted 7 not six colors in the spectrum
You’re thinking of indigo.
Red
Orange
Yellow
Green
Blue
Violet
That’s 6.
Perhaps it was the number I misremembered. There definitely is no violet in the spectrum
