I see a lot of fan mockups utilizing greens and blues in the colour palette. I think that's unlikely given the proximity of the Canuckleheads who seem to have finally settled on their colour scheme.
They could go green and gold (no NHL team currently using that) in anticipation of the inevitable Super Sonics return. Pluses and negatives to this approach.
Speculation is the seafoam green/coral red combination currently featured in their online channels. Seems a bit passive for an ominous-sounding team name in a sport that relies on intimidation.
They'd have to add a black or dark grey for it to work.
