Did someone tell you rainbows contain all the colors? Well, that's not true! It is missing a whopping 28% of colors!🌈

72% of all hues.

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.

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.

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..
