On the color wheel:

The color circle is an invention of Sir Isaac Newton and is basically
an artistic invention applied to a scientific analysis, given that he
had to synthesize new colors not found in the spectrum of colors he
observed from the prism. To construct his wheel he had to create
magenta and blue violet, blends of red and blue to, in effect, create a
crossfade from the low to high ends of the visible light spectrum.
Very much like crossfade looping an audio or video sample! Other
spatial models of color followed: Goethe, Maxwell, and other
"shapes"... triangles, cubes, cones, etc.
