citizen - I am not the BLM or anyother branch of  government!

Information about BLM adoptions
is offered as a service, to help
mustangs find homes and to
promote public appreciation of
wild horses and burros.

For information about the BLM
Wild Horse & Burro Program,
please call (866) 4MUSTANGS

Please direct adoption questions
to the BLM, not to me.

And I sure as heck am not a
Mustang car dealership!

I have NO horses or burros for
sale and am not interested in
buying or listing or otherwise
promoting your sale animals!

Disclaimer: I am not a geneticist. The information on these color pages represents the best scientific info I have been able to locate. Theories and knowledge change over time, and it may be you know something I don't - this site is not intended to be "the last word" in colors, just a guide for those wishing to explore the topic.

Color genetics are the same for all horses, regardless of breed or ancestry.

Since this is a Mustang website,
I use and prefer pictures of wild, or formerly-wild horses wherever possible.

CHART
of Colors

Colors and color patterns in mustangs are extremely varied, the inheritance of the early Spanish Horses who came in many colors and patterns.
- Dr. Phillip Sponenberg

Horse Color variations are so numerous, and they go by so many names, that it may seem impossibly complicated to understand. But understanding horse coloring does not have to be so hard.

Think of it as LAYERS, like painting with stencils or making wax-resist batik.

You start with a BASE COLOR: it will be one of two: Red or Black. That's all there are.

Every horse is, at base, either red or black.

The base color is determined by one "gene" - the Extension Locus. With the dominant form of Extension, the horse can be either red or black, but in reality will be black, except in the presence of a second "gene" - Agouti, which makes Bay, by restricting the black pigment to the "Points: (ear tips, mane, tail, lower legs).

In its recessive form the Extension Locus creates red pigment. All other colors and color patterns are created by the actions of genetic modifiers on these two base pigments.

RED (chestnut, sorrel)

BLACK
CHROME
"Chrome" is a term that refers to white markings on the face (stars, snips, blazes, aprons) and lower legs (socks, etc).

Chrome is determined genetically (by a color blocking agent) that may be an entirely separate component to coloring, or it may be part of certain pinto patterns.

Chrome is not considered in identifying the base color.

A horse may be any color or combination of colors and also have chrome - or not.


What About BAY?
Because many color genes affect BAY differently than Red or Black, BAY is also considered a "Base Color" although genetically it is the result of a genetic modifier ("Agouti") on the base color Black.


 

 

BROWN is not a color gene in itself. Brown comes about in many ways:

The most common useage of the term "Brown" in horses refers to a black horse or donkey with tan or lighter muzzle, and lighter mottling around the flanks.


Smokey Black may appear "brown."


Silver Dapples on Black creates "Chocolate"

Dark Red or Bay horses also appear "brown"

Here's a quick Pictorial Overview
of all the Known Horse Color "Genes"* (*common use, not technically correct) and how they affect  each Base Color:
Click on a link to go to a page about that subject:

RED BASE

BLACK BASE

BAY

 

AGOUTI (BAY modifier)
no effect on red;
may be carried "silently" by red

 

Agouti On Black
Creates BAY
>>>

Bay can range from almost buckskin to  almost black.

Bay foals are born with light legs and tails



BAY & "Wild Type Bay"A+)

CREME:
(One of the Four  DILUTION factors)
Creme is a mixed dominant, creating one effect if heterozygous and a more intensified effect if homozygous.



Single Creme: Palomino

Single Creme:
Smoky Black

(sometimes hard to identify - can be positively identified by genetic testing for Creme)


Single Creme : Buckskin


Double Creme on Red:
Cremello


Double Creme on Black: Smokey Cream
(Looks Cremello or Perlino but can be identified by genetic testing for Black and Agouti)

This Champion Welsh Stallion owned by Shirley Brand was tested by UC Davis to be Smokey Cream


photo: Greg Schultz
Double Creme on Bay: Perlino

Creme can also team with other dilutions (dun, silver, pearl, champagne) and other patterns (pinto, roan, etc) to create a spectrum of colors.
 

 

 

CHAMPAGNE
(another DILUTION Gene)

Champagne on Red =Gold

Champagne on Black


Champagne + Bay

 

Champagne + Creme on Red =  Ivory

photo: American Cream Draft Horses
Colonial Williamsburg Sour Cream (CW Sour Cream), reg. #230, and the colt is Colonial Williamsburg Cream Soda (CW Cream Soda), reg. #299

 
Champagne on Smoky Black

 

Champagne + Buckskin


DUN
(a DILUTION Gene)

Dun on Red = Red Dun
Claybank Dun

Dun can also team up with other color patterns for interesting effects:


Red Dun Sabino


Dun on Black = Grulla/o


 Zebra Dun, Bay Dun, Classic Dun

Also See DUN vs BUCKSKIN

 

 

 

 

 


Bay dun Tobiano

Dun on Palomino: "Dunalino"
"Linebacked Palomino"


Dun on Smokey Black
Looks light Grullo

This is a wild horse - the only way to tell for sure what color it is would be a genetic test - it could be a dunskin, too.


Dun on Buckskin
"Dunskin "
 

FLAXEN

is a recessive that dilutes red mane and tail to blonde or white

 No effect on Black but may be carried "silently"

 No effect on Bay but may be carried "silently"

FRAME
(Part of the OVERO paint/pinto group)


If you're breeding Frames, be sure to read: Overo Lethal White Syndrome

GREY

Grey/gray is a progressive color - actually a color replacing gene.

The foal may be any color (depending on the rest of its genetics) at birth. The gray gene causes the color to be gradually replaced by white hairs, bringing the horse through a roan-ish phase, then glorious dapple gray, then lighter and lighter until the horse is either almost pure white (but with black skin) or "fleabitten" gray (white with dark freckles or specks)

The famous "White Stallions" of the Spanish Riding School of Vienna, and the famous Lippizanner Stallions are grays in the final, mature white form.

 

 

 


"LP" - THE APPALOOSA COMPLEX:
Appaloosa coloring is complex, and recent research indicates that more than one gene is at work. Appaloosa coloring is not always stable throughout life, often becoming a "varnish" pattern at maturity.

PANGARE (Mealy Factor)


"Belgian Sorrel"

Maybe Seal Brown
(one theory)

Wild Type Bay

Angelo from Sinbad, Utah HMA

 

PEARL ("Barlink Factor")

Pearl was long thought to be just an especially shiny, metallic-looking version of Creme. Like Creme, Pearl is a mixed dominant, creating one effect if heterozygous and a more intensified effect if homozygous. Pearl can also team with other dilutions (dun, silver, champagne) to create a spectrum of effects.

No effect on Red;
may be carried "silently" by red

 

 


 

SPLASH
(Part of the OVERO PINTO group)

SOOTY / SMUTTY

WHITE
(Dominant White)

Genetic agent that completely blocks all color. But a genetically White horse has normally-colored eyes. A white horse is NOT an albino.
