Roan
A coat colour with white and coloured hairs mixed evenly across the body
No single value: Roan is a material, and its colour varies. The background shows its family, grey.
Roan is a coat colour seen in animals such as horses, cattle, dogs, and guinea pigs. It is marked by a fairly even mix of white and coloured hairs, giving a lightened or silvery look that does not fade with age. Roan patterns and their genetics vary between species, and the term covers several distinct genetic types.
- Roan is a mix of white and coloured hairs, not a solid colour
- Roan does not fade or lighten as the animal ages
- Classic roan in horses is a dominant genetic trait
- Blue roan, bay roan, and strawberry roan are common terms in horses
- Roan patterns and genetics differ between species
What colour is Roan?
Roan is a colour pattern found in the coats of several animals, most often horses, cattle, dogs, and guinea pigs. It is defined by an even mixture of white and coloured hairs across the body, creating a silvery or lightened appearance. Unlike grey, roan does not lighten further with age. The head, mane, tail, and lower legs in horses usually stay darker. Roan can be based on any underlying coat colour, leading to terms like blue roan (on black), bay roan (on bay), and strawberry roan (on chestnut).
Where does Roan come from?
The word 'roan' refers to this distinctive mix of white and coloured hairs, but the genetic causes differ by species. In horses, classic roan is a dominant genetic trait, though other patterns like varnish roan and rabicano can look similar. In cattle, roan is linked to a specific gene (MGF) on chromosome 5. In dogs and guinea pigs, the genetics are less clear or involve different genes. The term is used in animal breeding and show standards, with some breed-specific names.
How is Roan made?
Roan is not made from a substance but is a natural pattern caused by genetics. In horses, the Rn allele produces classic roan, while in cattle, the MGF gene is responsible. In dogs, the genes are not fully understood, and in guinea pigs, an incompletely dominant allele causes the pattern. The effect is always a mix of white and coloured hairs, not a solid or patchy colour.
Where Roan is used
Roan is mainly seen and described in animal breeding, showing, and identification. In horses, cattle, and dogs, it is a recognised and sometimes prized coat pattern, with specific terms for the different types. In guinea pigs, roan is also bred for, but double roan matings can result in health problems for the offspring.
Shades and relatives of Roan
Roan can appear as blue roan, bay roan, or strawberry roan in horses, depending on the base colour. Other patterns, like varnish roan, rabicano, and some forms of sabino, can look similar but have different genetic causes. In dogs, 'ticked', 'mottled', and 'belton' are related terms, with breed standards sometimes using them interchangeably. Roan is distinct from grey, which fades with age, and from brindle or magpie patterns in guinea pigs.
Questions people ask about Roan
What colour is roan?
Roan is a coat pattern where white hairs are mixed evenly with coloured hairs, giving a silvery or lightened look. The exact shade depends on the animal's base colour.
Where does the name 'roan' come from?
The name 'roan' describes this specific mix of white and coloured hairs in animal coats. It is used across several species, though the genetic causes differ.
Does roan fade as animals age?
No, the roan pattern does not fade or lighten with age, unlike grey coats, which become whiter over time.
Is roan the same in all animals?
No, while the appearance is similar, the genetics behind roan differ between horses, cattle, dogs, and guinea pigs.
What are blue roan, bay roan, and strawberry roan?
These are types of roan in horses, named for the base coat colour: blue roan is on black, bay roan on bay, and strawberry roan on chestnut.
