Equine color

ROAN

This horse’s coat mixes white hairs with another color for a speckled effect.

"Equine color" refers to the coat color of a horse, and "roan" is a specific pattern where white hairs are evenly mixed with another color like bay or black. It’s not a solid shade but a distinctive speckled look, often described as a "salt-and-pepper" effect. The clue is straightforward—no wordplay—just testing knowledge of horse terminology.
