I rescued a stray dark sable GSD so now I'm kinda partial to them. He was actually purebred and neutered too. Someone said they had seen him in a really bad neighborhood around the corner from where I found him and he was chained in their yard. When I found him he still had the latch from the chain hanging from his collar. Needless to say he didn't go back. GSD rescue took him.

I've seen the liver ones in pics, they are pretty too.
