This is an unusual situation. Last Feb. while shed hunting I ran across a dead buck. Since it was a pretty nice buck, I elected to have it mounted. My local taxidermist provided a cape (tanned). I just got the mount back and realized that I had seen this buck before. Looking through old game cam pics, I matched this deer to a piebald buck that was last caught on camera around Christmas of last year.
Here's a pic of the current mount:

Here's a pic of the original deer:

What I would like to do is to somehow dye the cape in the correct places to match the original deer. Is this possible? And what methods can I use. Someone I know mentioned the possibility of human hair coloring but my taxidermist didn't think this would work. Any ideas?
