Originally everyone just called her a roan but i'm not so sure anymore.
I've posted photos of both sire and dam, and think possibly, now, that her "roanish" coloring is just an excess of sabino??
I know the pictures arent the best as they were taken in winter when she was 6 months, but in the summer she did shed out to what appeared to be a nice, even-toned roan with a grey mane and tail.

This is the sire. He is a QH X Percheron gelding (now)
And the dam, I believe to be a pony mix of some sort. Her color is hard to see in this photo I know, but I will try to find any others I might have...
