Is roan the rarest equine coat color?

Roan is not the rarest equine coat color. It's actually quite common in certain breeds, like the American Paint Horse.

Here's why roan isn't the rarest:

* Roan is a pattern, not a color: Roan describes a coat pattern with a mix of white hairs intermingled with other colored hairs. This pattern can occur with various base colors, like bay, chestnut, black, etc.

* Many rare coat colors exist: Some extremely rare equine coat colors include:

* Champagne: A recessive gene that dilutes the base color, creating a pale, golden coat with a distinctive flaxen mane and tail.

* Pearl: A dominant gene that produces a pearl-like sheen over the base coat.

* Appaloosa Blanket: A specific pattern found in Appaloosa horses, characterized by a white blanket pattern covering the body.

* Cream: A recessive gene that dilutes the base color to various shades of cream.

* Dun: A primitive pattern with a dorsal stripe and zebra-like stripes on the legs.

It's important to remember: Rarity of coat colors can vary significantly depending on breed and location.
