Unfortunately, the hue color wheel does not correspond to human visual perception: Equal differences of the hue angle are perceived as different color differences. E.g. yellow takes only a small range of angles in the color wheel, see https://de.wikipedia.org/wiki/Farbkreis, second figure, for an example.
There are correctives for this issue such as Itten's color wheel.
My question: Are there equations that translate the angle of the hue color wheel into that of Itten's color wheel and vice versa? Of course, an interpolation of values at distinct angles could also work but equations might be better. Distinct angles are given here: https://uxplanet.org/algorithm-for-automatic-harmonious-color-selection-for-the-image-fc26dde69ca1#.lnuwum51m, halfway down.
