Copper is brown and tan...the colors show up better outside. There were 2 brown and tan and 2 black and tan in the litter. If you will look in the photo gallery you can see other pictures. I will try to get pictures next to my son's black and tan yorkie soon so you can see the difference in color. He is a very dark brown with tan markings. I have never seen one like him before. His nose was pink at birth and has turned a dark tan color now. It will be interesting to see what color he turns out to be.
