Roan

Common White Marking

Genetic Info
Genotype: Rn_
Locus:  Roan is a KIT gene mutation, along with Tobiano, Sabino, and Dominant White. A horse may carry only two KIT gene mutations.

(Images from left to right: Minimal Roan on Chestnut, Light Roan with Corn Marks on Chestnut, Intense Roan on Chestnut.)

Roan is a lightening of the coat visible across the horse's barrel, shoulders, chest, neck, and hindquarters.
It may cause a light, grayish appearance compared to the base color or turn the coat nearly white.
"Corn Marks" may form allowing the base coat color showing through.
Roan should fade gradually into the base color at its edges.
Notes:
  • Definitions:
    • Corn Marks: Small marks throughout the roan where the base coat may show through. These marks should be no bigger than a horse's iris and should not appear symetrical or intentional. They should never mimic false leopard in appearance.
  • Interactions:
    • Blanched: When Blanched and Roan are both present, Roan may be hidden.
    • Filigree and Kintsugi: Filigree and Kintsugi do not interact with Roan.
    • Chestnut: When Roan is on a Chestnut base coat, it is often colloquially known as "Red Roan."
    • Black: When Roan is on a Black base coat, it is often colloquially known as "Blue Roan."

  • Coat Color: Roan is a white marking.
  • Mane & Tail Color: Roan does not affect the mane and tail.
  • Skin Color: Roan does not affect skin color.
  • Eye Color: Roan does not affect eye color.
