Need Help With My Dog’s Coat Color!

[biancaaa]

Hi everyone. I posted about this topic on a different site about huskies, but I wanted some more opinions as well lol. My puppy is about five months old, and his coat is very confusing to me. The breeder told me he was a copper-banded wooly, which he technically is, but that’s not one of the standard colors, so I wanted to know if he fit in one of the standard categories. I included pics below! His undercoat is light beige, but the skin on his back is black, and it looks like the fur from the root is increasingly turning black, which I thought was not supposed to happen with red dogs. For some more background too, his dad is white and black with some copper spots, and his mom is dark agouti.
