One of the features of the Icelandic horse which makes it so unique is the variety of colors. Colors are not as important for breeders as they are in many other countries. And that is because you do not ride the color! Breeders are more concern about breeding the best stallion at each time than focusing on the color and that has lead to some colors almost got extinct. For a long time the grey color seems to be going extinct but luckily there are usually few grey stallions that are used for breeding.
