Well sunset/sunrise are names given for a type of line bred Northerns, but it's not a morph. I can't recall whether Caramel is also a line of Northerns or if it's a morph. As far as albino, I don't think there are any albino Northerns in the US. There are some awesome looking Northerns, unfortunately they're mostly all in Australia.
All the info you have given me has been great! Thanks and that’s a great looking skink!👍
