SgmSgm/nSgm
Stigma is a modifier that creates holes in other markings, and can also add an erased texture on the edges.
It cannot affect striped and spotted markings, as they are too small for the marking to display.
(Toxin, Marble, Drop, Ringed, Spotted, Banded, Dusted, Tuxedo, Jaguar, Poison, Striped, Tigris, Vertebral, Brindle, Clown, Dapple, Laced, Marble and Toxin)
Stigma will also not affect Cloud, Sabino, Gecko (as they can already display same effect) and all other modifiers.
In recessive it can affect 1 marking, while in dominant it can affect up to 3 markings.
