I'm ok with the colours. I think I would've preferred the Yellow/Green/White but this is still a pretty unique colour scheme. I'm happy that they didn't use the Seahawks colours and that they're going with something new. Vegas did well to stand out, looks like Seattle is doing the same.
I like the Sockeye's as a name. It's no Rain City Bitch Pigeons, but it's good enough for my books.
