Black Based Coats + DFP1

How Sooty and Dense Pheomelanin influence shade and expression of DFP1 on Black Based Coats.

Grullo Dun Brindle (E/e, a/a, D/-, DFP1/DFP1)

Unlike Chestnut and Bay based horses, Black doesn't react with Darkening Genes. So you wont see a color shift when adding Sooty, Dense Pheomelanin, or Sooty Plus. However you can get some variation using the Reroll option on the horses page. As you can see below, Dun Factor has a hard time showing up on Grullo horses. Black Based Dun horses are one of the less dynamic colors in the game.

Grullo Dun Brindle with Dilution Genes

Diluting genes change the intensity of pigment on a horse. However unlike on Chestnut and Bay bases, Black based horses with Dun Factor and Dilution genes look just as bold as they do without dilution genes. In some cases, they Dun Factor markings look even stronger when there are multiple dilutions. This is only unique to Black Based horses, and not on Chestnuts and Bays/Browns. Champagnes however get reverse dappling, and dappling can distort the Dun Factor markings.
