My lil Gucci man is black and gold and I am pretty sure he will stay that way. He hasn't cleared really anything at all lol not even on his head. I ADORE HIS COLOR!! I love the silver and tans as well but I prefer the darker. I don't know what his parents looked like, but I am sure you can get a black and gold from blue parents or a blue and silver from black parents. I get messages daily asking about how one can get a Yorkie like Gucci but to be honest, he just picked me and I am in love with him .. there was no science to that .. maybe a lil chemistry
I too see reddish hints in his coat from the sun
Here is his pic
