Design Guide

Overview:

• Genetics: ee __
• Skin: Medium/Dark Grey
• Eyes: Brown | Detail Guide
• Body should be medium reddish-brown, relatively even across the coat.
• Mane and tail should match the body, or be slightly lighter or darker.
• Does not have dark points on the legs.​

Variations:

• Liver Chestnut: Body becomes dark brown and less red/saturated. Mane/tail should be lighter than the body, often remaining a normal chestnut shade despite the darkening of the body.

Interactions:

• Dun: When Dun is added, the Phenotype is changed to "Red Dun" instead of "Chestnut Dun".
• Roan: When Roan is added, the Phenotype is changed to "Red Roan" instead of "Chestnut Roan".
• Flaxen: Chestnut and all dilutions (any coat with "ee" in the base) will be affected by Flaxen.
• Silver: Chestnut and all dilutions (any coat with "ee" in the base) will not be affected by Silver (listed as "Carries Silver").

Liver Chestnut

Overview:

• Genetics: E_ A_
• Skin: Dark Grey
• Eyes: Brown | Detail Guide
• Body should be brown or reddish-brown, relatively even across the coat.
• Mane and tail should be black. May have some slight brownish fading at the ends.
• Legs should be black to cover the knee/hock, blended where they meet the rest of the coat.

Variations:

• Seal Bay: Entire body should remain black except for the muzzle, eye, armpit, and groin/flank areas, which are brown. Legs should not have visible dark points, since the majority of the body will match them.
• Wild Bay: Black is restricted to the joints instead of the entire leg. Body should be medium to light bay rather than dark.​

Interactions:

• Roan: When Roan is added, it tends to be fairly desaturated/greyish instead of lightening to tan.
• Sooty: Sooty applied to Bay coats can sometimes be black instead of just dark brown.
  
  

Bay

Wild Bay

Seal Bay

Overview:

• Genetics: E_ aa
• Skin: Dark Grey; matches coat when coat is non-faded
• Eyes: Brown | Detail Guide
• Comes in a variety of exact shades, but should overall read as "black" at a glance.
• Coat can be slightly brown/red or even blue/purple in hue, depending on shade and fading.
• Mane/tail should match the coat color. No visible dark points on the legs.​

Variations:

• Faded Black: Black may fade into a lighter, browner, but still desaturated shade. Should not appear Chestnut or Bay. Mane/tail may also exhibit subtle fading at the ends.

Interactions:

• Dun: When Dun is added, the Phenotype is changed to "Grullo" instead of "Black Dun".
• Roan: When Roan is added, the Phenotype is changed to "Blue Roan" instead of "Black Roan".
• Silver: Black and all dilutions (any coat with "E_" in the base) will be affected by Silver.
• Flaxen: Black and all dilutions (any coat with "E_" in the base)  will not be affected by Flaxen (listed as "Carries Flaxen").

Genetics: G_
Locus: G

Overview:

• Greys are born as their base color and will progress toward white throughout their lives.
• You may design your horse at any stage of grey as long as it meets the minimum.
• Body greying should originate from the neck/throat, flank, armpit, muzzle, and eye areas and spread from there.
• Mane/Tail: Gradually lightens with the coat over the horse's lifespan; lightest at the ends.
• Skin: No effect
• Eyes: No effect

Variations:

• Fleabitten Grey: Body is lightened to white or near-white, with small "fleabite" spots dispersed across the entire body. Fleabites should be the base color, and should be present across the entirety of the coat, except where covered by white markings.
• ​Bloodmarked: Can be added to any form or stage of grey. Bloodmarks are patches of color unaffected by grey, most often seen on Fleabitten Grey as an area of concentrated fleabites. These patches will show the base color beneath with no lightening. Edges should be textured.​

Interactions:

• Rift: Will gradually desaturate Rift throughout the lifespan, but does not always cause it to lighten/grey out.

Range:

• Minimum: Must express obvious lightening in at least 2 of these areas: neck, flank, armpit, face (muzzle/eyes).
• Maximum: Body, mane, and tail are completely white; skin and hooves will remain consistent throughout lifespan.

LpLp patn = Snowcap Appaloosa, LpLp = Varnish Roan, LpLp patnpatn = Fewspot Appaloosa

Overview:

• Causes a white "blanket" starting at the rump, with an assortment of oval-shaped holes/spots that reveal the base color beneath.

• May have small dark spots scattered within the blanket and slightly outside of it, and may have white spots scattered slightly outside it.

Hazelnut Sabino

Blueberry Roan Sabino

Chestnut Sabino

Genetics: O_
Locus: O
Lethal White Syndrome occurs for "OO" Overo horses, and is fatal. If a foal geno is rolled as OO, it will be marked unusable. With this in mind, it is possible for a breeding to fail completely if two LWS foals are rolled, and the slots will still be used up if this occurs.

Overview:

• Causes irregular white patterning that starts from the belly and/or center of the horse. Markings should have cutouts around the edges to cause irregularity of shape and sharp edges. Will not round outward.
• White generally spreads within the center area of the horse, creating a "frame" of color around it. The only areas on the body where it may cross to the other side of the horse are the crest of the neck and the belly (from behind armpit to just past groin).
• Can cause extensive and/or irregular face markings, generally bald faces with some cutouts. May cause badger face.
• Mane/Tail: White in mane where touching; will not affect tail, as it cannot cross/touch.
• Skin: Pink skin beneath white markings.
• Eyes: Blue (optional)

Range:

• Minimum: May be fully hidden if desired.
• Maximum: White markings on the vast majority of the body, not crossing the "frame" of the body except on the neck/belly. Significant white markings on the face and legs.
  
  

Blueberry Overo

Chestnut Overo

Genetics: W_
Locus: W
Lethal White Syndrome occurs for "WW" Dominant White horses, and is fatal. If a foal geno is rolled as WW, it will be marked unusable. With this in mind, it is possible for a breeding to fail completely if two LWS foals are rolled, and the slots will still be used up if this occurs.

Overview:

• White marking with extensive coverage., often making the entire body pure white.
• If incomplete, edges should be textured - may be jagged or powdery, similar to Sabino.
• Mane/Tail: White where touching.
• Skin: Pink skin beneath white markings.
• Eyes: No effect

Range:

• Minimum: Similar to high-coverage Sabino. Should have white markings across at least 50% of the barrel/neck (scattered, not just a perfect split), high leg white (at or above knee/hock), and extensive face white.
• Maximum: Body, mane, and tail are completely white.
  
  

Dominant White on Bay

Dominant White on Red Roan

Dominant White on Black Pearl

• Mane/Tail: Tail must have either gradiented white at the root, or "skunk tail" (ribbed/striped white at the root; see examples).
• Skin: Pink speckling/mottling (optional)
• Eyes: No effect

Range:

• Minimum: Some expression at the groin only; must be noticeable, around the size of the hoof at minimum.
• Maximum: Vertical coverage that does not cross/touch topline. Horizonal coverage to armpit and first third of hindquarters.

nLp = Snowflake Appaloosa, nLp patn = Blanket Appaloosa, nLp patnpatn = Leopard Appaloosa
LpLp patn = Snowcap Appaloosa, LpLp = Varnish Roan, LpLp patnpatn = Fewspot Appaloosa

Overview:

• Creates an irregular roan-like expression, often with some spots/holes and large blended sections taken out.
• Typically extends on to the face, unlike typical roan, and is patchy in the most bony areas (hips, withers, joints, face, etc). Patches should be textured/powdery.
• Can also exhibit spotting (holes in the pattern), though this should be kept sparse and should not appear Leopard-like.
• Please note that Varnish Roan is considered a white marking, and therefore should be white rather than low-opacity like normal roan. The pattern should appear as a white marking and not just an overlay.
• Mane/Tail: No effect
• Skin: Pink skin beneath white markings, optional pink mottling on unaffected skin.
• Hooves: Optional tan/shell striping.
• Eyes: No effect

Range:

• Minimum: Covers the body and neck, leaving the head and legs alone.
