My filly was born dark true black. Her sire is chestnut gone gray and her dam is a blue roan (Ee aa RnN). I know the filly is turning gray because she is starting to get goggles. She was born with 1 white eyelash. As she has gotten older her coat has started to turn brown with lots of white hairs mixed in. On her back two legs they are turning a tan or fawn color. Is she fading from the sun?? Is she black? Her nose looks black to me and not brown. My thoughts are blue roan filly going gray. What are yours??
