homozygous for red pigment (ee);
may have any agouti genes.
horse with red pigment only is a chestnut. The color names
chestnut and sorrel are used in different ways by different people. They
are genetically the same color, red (ee).
The shades of chestnut range from
"blond", as in the American Belgian horse (at bottom) to "black
chestnut", as shown by some of the Arabians on the web site
A very dark chestnut may be called a
"liver chestnut" or even a "black chestnut". A chestnut may have a
white, or flaxen, mane & tail.
Halam, an Arabian, is registered as a chestnut.
His is the typical, bright-chestnut color. The light-colored
hair on his lower legs, clearly seen if you click this
picture, are characteristic of many chestnut horses, and is commonly called
"pangare" (pan-guh-RAY). No one knows yet whether this is a
separate gene, or how it's inherited.

Irish Empress by The Scarlet Irishman and her filly by Mr
JB Dude. These two are the lighter chestnut, sometimes called
sorrel. Owned at the time of this photo by Barbara
Burton; sorry, this photo is actual size.

colt looks like what some call "sorrel" in this early pic,
left ... but it's just
"foal leg color". His legs were as dark as his body when
he matured, all of the way down to his hooves.

To see some amazingly colored chestnut Arabian
horses, check out
this thumbnail sized photo to see an American Belgian horse, which is an
example of how light a horse can be without having any of the known
body-dilution genes. This color is commonly called "blond
chestnut" or "blond sorrel". This is also an example of a "flaxen chestnut". Flaxen is
considered a dilution gene but only dilutes the mane and tail.
Also, pangare is at work here... but the main body color is still a very
light shade of chestnut.
