Long-coated German Shepherds are my favorite (sorry Bianca
) or plush coated. I like all the colors GSDs come in, but for the saddle back type I prefer either the rich red, or silver (not so much the in-between tan colors.)
If I had to pick favorite colors I'd say black and red, black sable or red sable.
I think the disqualified colors are gorgeous too (blue, liver, "panda" etc...)
