A grulla is a BLACK horse with the DUN gene/dilution
No dun stripes? NOT A GRULLA
Grulla is just a color, not a breed of horse. So just what color is Grulla? It's often described as a silver, mousy-gray, smoky-blue, or slate-gray color, even a charcoal shade.
The dorsal stripe, head and legs are darker than the body. Since the dun gene is all that separates a grulla from a black horse 'dun factor' (dorsal stripe, stripes on legs, ear tips, shading on legs, shoulders and even face) are almost always DISTINCT.
The following shows what color results from three base horse coat colors when the dun or cream genes are passed by a parent to an offspring:
Sorrel + Dun = Red Dun
Sorrel + 1 Cream = Palomino + 1 Cream = Cremello
Bay + Dun = Dun
Bay + Cream = Buckskin + 1 Cream = Perlino
Black + Dun = Grulla
Black + Cream = Smokey Black + 1 Cream = Smoky Cream
Red Dun + Cream = Palomino/Dun (Dunalino)
Dun + Cream = Buckskin/Dun (Dunskin)
Grulla + Cream = Smoky Grulla
