There is a possibility your centaur is born carrying multiple color-altering mutations. 
In that case, the centaurs owner can choose which mutation is visible, and which one carried and not shown. The design cannot show multiple color altering mutations  simultaneously, unless it has the chimera mutation and.

Sagittari doesn't have separate inbreeding only mutations.
