My mare, Gypsy, is a grey arab (no papers but she appears to be small pure arab) with a bay base. However she is 10 years old, and in the 5 years that I've had her coat color has barely changed at all. Her legs have gotten lighter, the left front used to have a kind of salt and pepper look, while now its almost completely grey up to the knee. Also her other legs have spots of grey in them as well now. She does tend to get lighter in the winter and shed out to be darker in the summer. I was told once that most horses, if they were going to grey out would be almost completely grey by the time they are 10, or atleast much more grey then Gypsy is now... Is she slow at greying out or is there something I'm missing? Also what would you call her coat color? If I just say 'grey' most people think something more like the color of my gelding. I sometimes say a rose grey, but I thought that was just greying chestnuts.
Here is the first picture I can find of her taken spring or summer 5 years ago. Its bad quality, but atleast you can sort of see the coat color...:
And then a picture taken last winter:
And a picture taken this summer (couldnt find any pictures of her standing still, sorry):
