I understand the concern for the horse, but that had nothing to do with the OPs question. Let's focus on that, since the OP has made it very clear that she's well aware of the horse's condition and is doing what she can.
Extreme criticism is neither productive nor appreciated, and, in this case and in my opinion, completely unwarranted. In fact, some of you were downright rude about it. That's a huge pet peeve of mine. There is a huge difference between constructive and destructive criticism. Off my soapbox now. :)
Back to the real question at hand, with his winter fuzzies, he looks red dun to me as well. Maybe he's one of those color-changing horses that seem to be a completely different color in the summer and he'll look more like a palomino then. Posted via Mobile Device
