What defines a Blue Roan horse's color?

A Blue Roan horse is characterized by its unique coat color, which consists predominantly of a mixture of black and white hairs. This gives the horse a bluish appearance. The correct answer highlights that these horses can have a blue-black base coat, often with some red hairs interspersed, which adds to the roan effect.

This distinctive coloration is the result of a genetic combination that dilutes the black coat while leaving some red hairs in the mix. The phenomenon creates a striking and memorable appearance that distinguishes Blue Roan from other coat types. Other color patterns typically differ in both genetic makeup and visual impact, which is why they do not fit the characteristics of a Blue Roan horse.
