Buckskin is not a breed of horse but a color. There is a buckskin registry but it has nothing to do with the breed of the horse but his coat color. The Pinto registry is the same thing. The Buckskin registry will take any breed of horse as long as it has the buckskin color.

People were breeding 'Quarabs' long before the first breed registry formed in 1984, the first registry closed however and the international Quarab horse Association formed in 1999 and is the leading registry for the breed.

Falabella's can be any equine color, the breed registry does not limit the colors and patterns found in the breed.
