Brown Dun
The brown dun ("brunblakk") is the most common color. It can be found in lighter or darker shades. The color of the body is pale yellow-brownish, and can vary from cream yellow to nearly brown. The "midtstol" (the darker stripe of hair in the middle of the mane), dorsal stripe and "halefjaer" (darker hair in the middle of the tail) are black, or dark brown. The light colored horses have white forelocks and white hairs on the mane's outside. On darker individuals, these hairs are also darker.

Red Dun
The red (chestnut) dun's ("rodblakk") body-color is pale red-yellowish, and can also be seen in lighter or darker shades. In some cases, it can be difficult to tell the difference between a brown or a red dun. On the red duns, the "midtstol", dorsal stripe and "halefjaer" are red or red-brownish, always darker than the color of the body, but never black. Mane and tail are mostly very light or yellowish. On the lighter shades of red duns, the forelock, mane and tail can be completely white. When they are foaled, the red duns can have white hooves, but the hooves will darken as they grow older.

Grey Dun
The greys have a body-color which can vary from light silver grey to dark slate grey. "Midtstol", dorsal stripe and "halefjaer" are darker than the main color. Forelock and muzzle area are dark in contrast to the brown and red duns who mostly have a light forelock and muzzle area. On the darkest individuals, the mane and tail can be very dark. If one had used the same pattern in naming this color as in the naming of the others, grey should be called black dun, but this term has never been used.

Uls or White Dun
Uls dun ("ulsblakk") is a variety of the brown dun color caused by a factor which reduces the production of pigment, so-called diluted color. The color of the body is almost white or yellowish-white. "Midtstol", dorsal stripe and "halefjaer" are black or grey. Mane and tail has a lighter shade than the body.
Yellow dun ("gulblakk") is the rarest of the Fjordhorse colors. It is a variety of red dun caused by the same factor as mentioned under uls dun. The color of the body is yellowish-white. "Midtstol", dorsal stripe and "halefjaer" are darker yellowish than the color of the body. Forelock, mane and tail can be completely white, and on such individuals the dorsal stripe can be indistinct.
