Color Question

I'm trying to figure out what color this pup is. I have no idea what color he is. His background is an agouti berkshire and an amber male.

Unfortunately this rat pup did not survive, but I'm curious as to his color. I'm not sure if I posted about him before, but I did look first before posting. His parents are both agouti based colors, but they carry black. They also carry PEW and dumbo.

Note: Because the father is amber, he also carries PED (pink eyed dilute).

looks like a blue of some sort with a blaze stripe

It's possible that he was a platinum, but since he did not survive, there really is no way to tell for sure. Rats molt over their lifetimes, so coats change color often. He sure was a pretty little guy, though. Sorry he didn't make it.
