There are approximately 5,000 base colors, plus a couple hundred
Those colors are sometimes translucent and layered over each other
There are approximately 37 sextillion basic color/pattern variations, including current mutations (75 genes each with at least 2 outcomes each)
Plus each individual has a unique seed that can effect the way some markings display, for example, every pattern of pied white is unique
So... there are about as many phenotypically unique Khundii as there are atoms in the observable universe, and theoretically infinitely many distinguishably different designs.
