The retrieved sources individually discuss how the linear visible light spectrum differs from a cyclic color hue wheel and how color vision is a neural construct created by the brain, but no single source comprehensively couples both aspects to fully establish the claim.

## Question
The following problem has bugged me for a while, ever since I noticed it. On the Visible Spectrum Wikipedia, the following is the visible spectrum:
Now, in Photoshop, or really any colour picker, the hue slider looks something like this:
Or sometimes this:
I noticed that in both of these, the colour loops back to red. Why is this? I believe that this doesn't happen on the visible spectrum. The visible spectrum goes from a violet-ish colour to a maroon-ish colour, with a whole range in between. But where does the magenta colour from the hue slider fit in?
I take it that it is possible to have a purely yellow object, or a purely teal one, as it is on the colour spectrum, yet are magenta things and pink flowers inherently reflecting multiple wavelengths of light, from opposite ends of our particular viewing spectrum? All of this seems awfully odd to me, so I was hoping someone might be able to clear it up.

## Introduction
Color vision is an illusion created by the interactions of billions of neurons in our brain. There is no color in the external world; it is created by
