Note: This does not change the other values, i.e. the color cycle. Therefor, the method can just be used to skip steps (i.e. colors) in a cycle.

Creates a list of around 36 different colors, where one is easily distinguished from the preceding one.
The list of colors starts with a fully saturated, full valued red (Hue = 0 = 360). After that the sequence is generated like this:
Finally repeat colors.
