The Encylopedia Of The Selcarim (pg 3)

The Selcarim is most commonly found in dark colors. In fact, many of the wild herds believe that dark colors are signs of mental and physical strength as well as good health. Darker colors are highly prized in the wild and so are the most popular. Dark bay is the most commonly seen color, often with a red tint to them. Other bays are also more common than other colors and the darker the better. Black is  also quite common, though because bay is so commonly seen, blacks are still rare in comparison to bay. Black horses are honored above all others in the wild as they are the darkest.

Pretty much any dilution color is rare, though there are some that are seen slightly more than others. Such colors as dun and roan variations are uncommon, but not rare and not exactly hated, but still frowned upon to some extent. Grey is a little more uncommon than these, but not as rare as such colors as chestnut or colors caused by other dilutions.

Though with other common breeds, chestnut may be something seen often, it is not so for the Selcarim. Because dark colors are seen so highly in the wild, most chestnut horses do not get a chance to breeding. After years of selective breeding by the wild herds, chestnut has become very uncommon. They are still seen occasionally, but they are never treated well in the wild and hardly get a chance to breed. Luckily most herds will not kill chestnut foals, though they will be pushed around by the others.

Cream has a strong affect on the base color and lightens it dramatically. Because of this, it is very, very rare to be seen in a Selcarim. Usually the only cream horses that are not killed at birth are blacks (as cream does not greatly affect black base colors) and buckskins, though sometimes even buckskins are killed, depending on their shade. Double cream dilutes are obviously killed immediately with no second thought. Often a mare who bares a double cream foal (such as a cremello or perlino) are forbidden to breed again and on rare occasions even killed along with the foal.
Champagne is also an extremely rare color, though it is actually seen more often than cream. This is only because when the foal is born, it is darker in color and so not killed. However, the Champagne gene affects the red in the Selcarim's red eye, lightening it to more of a pink color at birth. Though this changes as they grow older, the herds have learned this to be a sign that the foal will 'loose it's color' as it ages and will kill it. Champagne foals are called the 'hidden ghosts' and those who live to grow past a foal are feared and often attacked by all others.

A Selcarim's mane and tail is always the same color as their markings and is determined by the same genetics. The three most common colors are dark brown, medium brown, and light brown, with light being the rarest. Some stallions will kill a foal born with light brown markings if they are too light, although not always. Often the thing that determines weather they are killed or not is weather or not they are the lead's foal. As well as these there is also the black marking color. The black is dominant over all other colors, though it is not as common as the others. It appears that black markings are something that has appeared recently, most likely a genetic mutation, and so it has not spread very far yet.

The rare colors for markings are cream and white. Both are extremely rare and a foal with these colors will be killed at the instant of birth. White has nearly been whipped out of the breed completely though the cream can be seen often still, and this is because it can be hidden (see Genetics to learn more).
