Ok, I know the standard color combos are Blue/Tan, Blue/Gold, Black/Tan, and Black/Gold. And, I know the difference between blue and black now...that's pretty obvious!! BUT, what I don't know is what is "tan" and what is "gold"?? I know I have seen Yorkies with a lighter, almost platinum blonde head and legs, and have also seen some with a much darker, richer color mostly on their little heads, but I don't know which word goes with which color, OR if I'm wrong altogether and the "gold" is something I haven't run across yet?? Please school me yet again

.....maybe an example pic of each would help me get it!?
Thanks so much!
