These are photos I took of a Spanish bred mare at the 2010 All Breed Show. I'm not entirely sure, but this horse could be either Sonhos Balarin or Hanna Indiana. I suspect she's a Lusitano, but I could be wrong.
I know dilutes occur in the Spanish breeds, and to me this mare looks to be either buckskin (she has a clear dorsal and at least parts of the mane and tail are black/dark), or grey over an unusual base. But what do you all think? Could she be a brindle or am I just seeing a painted zebra?
