A look at marble appaloosa horses around the world and on a variety of different breeds.
Varnish roan may look like (and are often mistaken for) roan, it is not the result of the roan white pattern or a grey modifier. They are the result of the Leopard Complex and are born the base color (often with some spotting) and they begin to blur or fade as they age. Animals often retain their base color over bony parts (also similar to roan).
