Thank you! ^^

Tobiano, splash white, rabicano, Sabino and frame overo

Then thereÂ’s the appalosa patterns

Leopard, blanket, snowcap, fewspot, varnish and snowflake

And the randomness that you can breed or get with rerolls

Sooty (dark hairs, sometimes appears as dapples), pangere (Light hairs), chimera (can come in dark bay, light bay, black, pearl, chestnut), birdcatcher (random whit spots), bend-or (ink blot like spots, black spots) and lace

Then the white or black brindle (not inheritable)

The three main horse colors are Red (variably called Chestnut or Sorrel), Agouti (Type 1 Bay or Type 2 Seal Brown) and Black.

Then you have modifiers like Dun, Cream, Champagne, Pearl, Silver, Roan

Patterns like Frame, Tobiano, Sabino, Rabicano, Splash White

Leopard complex (appaloosa with or without patterns)

Greying gene

Dominant White

Some colors have special names.

Black Dun is Grullo.

Cream Black is Smoky Black

Cream chestnut is Palomino (and a dun Palomino is a Dunalino).

Double cream chestnut is Cremello.

Cream Bay is Buckskin (and a dun Buckskin is a Dunskin).

Double cream bay is Perlino.

Black roan is called "Blue Roan"

Black roan with Silver is called "Silver Roan"

Chestnut Champagne is Golden

Bay Champagne is Sable

Black Champagne is Classic

Apricot is a special color that requires the pearl and cream gene both.

Grey foals are always their base color and turn lighter grey throughout their life (they change at age 3 on the game).

Then there are variations of colors.

Buttermilk Buckskin (more "golden" color)

Chocolate Palomino (darker color)

Flaxen Chestnut (blond mane)

Liver Chestnut (darker red)

Blood Bay (darker red body)

Sooty (darker hairs usually on the back)

Pangere (lighter hairs usually on the stomach)

And there are colors/markings that are not defined by genetics here (not directly inheritable on the game, though they may have some genetic basis in the real world)

Birdcatcher spots (white spots)

Bend-Or spots (black spots)

Chimera (when twin embryos fuse into one foal)

Brindle (which may be a variation of chimerism).

I'm sure I'm missing some, but you can see that all the genes in the list past E and A are just modifiers on the basic colors.
