The space of visible colors is three-dimensional, and the spectrum is missing two dimensions (brightness and saturation). You can’t assign a percentage to that.

Exactly! And that is what I say in the video. Just that I tried to find a simple title.

... also there are different choices for the scaling of the hue axis, so the percentage can change. This is also noted in the vid.

Well there is wavelength and intensity, an all together it is called a spectrum. No need for a third parameter. Also there are mor than 100% of all colors in there, as a quick check on Wikipedia would reveal..

The third parameter is saturation, which comes into play for non-monochromatic (i.e., multiple-wavelength) colors.

I agree

There is no such thing as a mono wavelength color. There are only spectral densities. Or in other words electromagnetic radiation / photons distributed over some energy.

Is this a weird terminology argument? Because there are definitely ways to produce color that output one specific wavelength of light.

Yes at exactly 0K and without quantumechanics..
