This is my 16 year old appaloosa mare. I am not sure if she was registered, and if she is her papers were never given to the therapy barn that I got her from.
Anyway, I think she started out life as a chestnut and roaned out, but would love other people's impressions of her color/pattern. She is mostly white skin with a lot of black "splotches" under her white coat, most heavily on her neck, chest, shoulders, and "arm pit" area. She has lesser amounts of black splotches on her back and rump. She also has chestnut colored "flea bites" on her, but they are not nearly as regular or numerous as you would expect to see on a flea bitten gray.
Sleepy pony. Insides of her ears are still chestnut, and the outsides of her ears look like what a chestnut turning gray would look like at the stage where you could still tell that they are chestnut, but they are turning gray (if that makes any sense)
terrible attempt at getting a confo shot. I would get her to set up square, turn around to get the camera, turn back around and she looked like this. I gave up after the fourth botched shot.
This was for a saddle fit picture, but you can see the black spots really well.
And her interesting leg markings:
And, just because she's cute:
