My little friend, Shelby, is wondering about the rarest horse color? Any ideas?

I'm guessing the color dun, an almost neutral brownish gray to dull grayish brown.

I'd guess the native american horse called the 'paint', since there are so few of them out there. I lived in northern Cal. for 5 incredibly long years, and one of our neighbors had 5 or 6 paints. They varied in color, but the pattern was very distinctive.

According to the American Buckskin Registry Association, Inc. (ABRA) the rarest horse body coat color of all is "Grulla" (Grew-ya), a color that could be described as "slate-colored." You can click here to view detailed information on this color.

There are also "rare" colors by breed, e.g. in Arabians, the rarest color is probably black.

Although not actual colours as far as a colour chart is concerned,i think that Albino and Appaloosa horses must be among the rarest in colours,certainly here in the UK,an Appaloosa having a white background and black spots and an Albino having body, mane and tail that is extremely pale, almost white .Dun and Palomino horses must also be contenders,though I have to disagree with jerseytomato's description of the colour Dun,"an almost neutral brownish gray to dull grayish brown"? this is usually described as "creamy gold"! also Duns have black mane and tail and a black stripe down their back,where as a Palomino has a similar colour coat but white mane and tail.

Anyone who finds pintos a rare color hasn't been to the west coast. There are tons of pintos here. Quite a few palos too.

We have a buckskin quarter horse..I don't think it is a rare color though.

LVLF, Paint horses aren't rare at all. Maybe only where you live, because where I live I've seen lots of them. I'm hoping to have one in the future because my boyfriend's dad wants to get rid of all their horses, one of them is a paint and Matthew( boyfriend ) says that when the time comes he'll buy Cheif (the paints name) from him. I've seen many more in newspapers, and I hear that the horse auction in Iowa has seen a number of them.
So you can really only say that they are rare in your neck of the woods, 'cause they thrive here!

I'd have to agree and place my bets on "Grulla" also as being probably the most rare. True Blacks are not exactly common, but I wouldn't consider them rare either. Another not often seen is a "Blood Bay." While there are lots of Bays out there a true deep red Blood Bay is not one you catch a look at everyday!
