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.

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.

Pangare Chestnut

Pangare Buckskin

Pangare Chocolate Palomino

Genetics: Sf_
Locus: Sf

Overview:

• Causes speckling as if snow has collected on the topline and/or around white markings. You may choose one or both when designing!
  • Topline: Concentrated on the withers/back, as if snow has been sprinkled on the horse.
  • Marking: Concentrated on the border of the markings, and sprinkled slightly outward.
• Spots can vary in density and size, but should be smaller than the eye. Bigger patches are caused by dense spotting that merges.
• Spots should become sparser the further they are from the main concentration area, so that there is noticeable taper in density.

Range:

• Minimum: Must cover the withers or attach to at least one white marking - it cannot be completely hidden.
• Maximum: Snowfall along the topline and all markings. Topline concentration should only cover about 1/4 of the barrel vertically.

Genetics: Co_
Locus: Co​

Overview:

• Causes a white band around the barrel.
• Should not be perfectly smooth; edges should have some degree of variance.
• Thickness can vary slightly, but should be fairly consistent from top to bottom.
• Must begin at some point on the first 1/3 of the back (measured from start of withers to point of hip).
• Cannot start further up than the start of the withers, nor end further back than the hip.
• Mane/Tail: No effect
• Skin: Pink where covering
• Eyes: No effect

Range:

• Minimum: Should be at least as wide as the withers.
• Maximum: May cover the entire barrel from withers to hip.
  
  

Almond Corset

Grullo Corset

Genetics: St_
Locus: St​

Overview:

• Stained may present in two different forms. You may freely choose either form when designing, but not both.
• Causes parts of the coat to be darkened - area/amount is dependent on the version chosen.
• Darkening should be medium/low-opacity, keeping underlying variance intact (dapples, countershading, etc).
• May exhibit darker or lighter mapping around the stained markings.
• Version A:
  • Causes 1-3 random independent patches of the coat to be darker.
  • ​Patches should have edges with cutouts, similar to the shape/edges of Overo.
• Version B:
  • Darkens some or all of the white markings on the horse. Adheres to all rules/bounds for the marking, just makes them dark.
  • If a marking is darkened, it must affect all white that physically touches it, even if caused by two different genes.
  • Natural white may be applied on top after staining if desired (this is the only exception to the "all white that touches" rule above).
  • Affects everything listed under "White Markings" on the Visual Hierarchy page.

Interactions:

• Halo: Mapping on Version B can be affected by Halo, darkening the Halo as well if the main marking is Stained.

Range:

• Minimum:
  • Version A: At least one marking as large as the head.
  • Version B: At least one marking affected.
• Maximum:
  • Version A: Up to three different markings, not exceeding more than 1/3 of the body total on each side.
  • Version B: All white markings are affected.

Genetics: Bl_
Locus: Bl

Overview:

• Creates numerous holes in white patterns.
• Holes can vary in distribution/amount but should be somewhat oval in shape.
• Size of the holes should generally mirror Appaloosa spots, but can be a bit smaller (should not resemble fleabites).
• Can affect some or all white markings on the body, including natural white (face/leg markings).
• Affects everything listed under "White Markings" on the Visual Hierarchy page.

Range:

• Minimum: May be fully hidden.
• Maximum: May affect all white markings on the body. Must be clearly identifiable as spots/holes, not large patches.

Genetics: Dt_
Locus: B | Ty | Cv | Dt | D​
CvDt = Civet, TyDt = Tabby, BDt = Bengal, DtD = Primitive Dun, nDt/DtDt = Primitive Dun

Overview:

• Dilutes the body, leaving the legs and head alone (may reach the cheek slightly).
• A modified form of Dun. Causes an exaggerated expression of primitive markings.
  • Leg barring and dorsal stripe are required, while shoulder barring and facial cobwebbing are optional.
  • Will extend, thicken, and overall exaggerate the stripes in these areas.
• Stripes must clearly radiate from normal dun markings, and should taper at the edges. 
• Stripes on the front half of the body should be vertical, may not cross the throat/underside of the neck, and should stop just after the withers.
• Stripes on the back half of the body should be horizontal, stop at the dock of the tail (not continue on to the back), and should not pass the hip.
• Stripes on the front legs will gradually transition to become more vertical as they meet the markings coming from the topline.
• Primitive markings should be a few shades darker than the points, or black if points are already black.
• Mane/Tail: May exhibit light "frosting" blended at the roots of the hair.
• Skin: No effect
• Eyes: No effect

Interactions:

• Civet, Bengal, and Tabby: When paired with these genes, Primitive Dun will be hidden and have no effect.
• On renamed Dun combos, "Primitive" will be written before the color rather than after (Primitive Grullo, Primitive Red Dun, Primitive Dunalino, etc).

Range:

• Minimum: Dilution (lightening) of the body, as well as leg barring and dorsal stripe. May look like normal Dun at minimum.
• Maximum: Extension of all primitive markings (leg barring, shoulder barring, facial cobwebbing) to the bounds described above.
