Dun on Black: Grulla
Shaila, a 3 YO (in these pics) AQHA/NFQHA Grulla mare - Tested Ee aa, neg cream, neg LWO, and is Dd, with year-round brindle pattern (see pics below). Photo contributed by Tara, www.risingmoonranch.comGrulla is the name for one or two dun genes on solid (non-bay) black.It's a Spanish word, the name of a crane that's a mousy gray color like these horses often are. It's pronounced "groo-ya", correctly, though not always.Because they are a dilution of true black, grullas will often be a "cooler" color (not warm/red/orange) than other duns. Their points will usually remain true black, as do their dun markings.Many say that a mostly-black head is a good indication of grulla. Others go by a muted or dark body shade. For this page, however, I'm only showing genetically-proven examples. A horse is a "proven grulla" if it tests to have at least one E (black based), aa (no agouti/bay) and no cream gene ... plus it must have a dorsal stripe and leg markings on at least two legs.I hope, by this method, to establish what a "real" grulla *usually* looks like, and what a "real" grulla *can* look like.Study of "True Grulla" #1, "Shaila":Grullas can be any body color from slate blue to brown to silvery to nearly black. We don't know if this is due to variations in the dun genes, the base color (black), or both!"True Grulla" #2, "Blue"
True Grulla #3This horse of Mary Hass' is a less expected color, yet did test true: E_aa, no cream! http://www.haashorsefarm.com
