Not sure where the station is getting their info. From nearly all accounts, Kraken has been off the table for a while. Neither the team nor the NHL seem particularly keen on the name.
As for the colors, it's notable that they didn't start using these colors until the team's official NHL team site went live. Prior to that, they were still using the generic black, white, silver/grey, and red. Considering all NHL team sites are dressed in team colors, I would lean more towards the side of these being the Seattle team colors than not.
