They'll also need to decide upon a colour scheme, and that's what this post will focus on. Below are 20 colour schemes that the Seattle ownership group could consider, starting with a few different green options (Seattle is called the Emerald City after all).
Note: Seattle HC (Hockey Club) is just a placeholder name. That's not what I think they should be called or anything.
Light Green, Dark Green, White
Light Green, Dark Green, Gold, White
Although, maybe they should directly copy the colour scheme of another Seattle sports team. It wouldn't be the first time that teams in a city shared a colour scheme (Pittsburgh is probably the best example). Here are a few options if they want to go that route.
Green, Blue, Silver, White (Seattle Thunderbirds)
Navy, Bright Green, Silver, White (Seattle Seahawks - 2012 through Present)
Blue, Navy, Bright Green, White (Seattle Seahawks - 2002 through 2011)
Bright Green, Shale, Blue, White (Seattle Sounders FC)
Blueish-Green, Navy, Silver, White (Seattle Mariners)
Dark Green, Yellow, White (Seattle Supersonics)
Moving on from existing (or pre-existing) Seattle colour schemes, let's try a few red based options (I doubt red will be their main colour, but the Seattle ownership group has been using red for some promotional stuff).
Red, Green, White
Red, Black, Turquoise, White
Coast Salish artwork. It's also a unique colour scheme, the only team (I can think of) that used anything similar were the NBA's Vancouver Grizzlies.
Red, Brown, Sand, White
Okay that's enough red for now, let's get back to some more green colour schemes.
Green, Brown, White
Dark Green, Burnt Orange, White
Dark Green, Light Blue, White
Green, Navy, Light Blue, White
Green, Navy, Red, White
We'll finish off with a couple of brown options, and one black choice. I'd be very surprised if they did go with brown as their primary colour, and I hope black isn't, but I thought I'd include them anyways.
Brown, Dark Brown, Light Blue, White
This double brown and light blue colour scheme is entirely based off of Ross Hettinger's fantastic Seattle SeaLions concept. I really liked how unique these colours were, and I thought they'd work well in Seattle.
Brown, Dark Brown, Bright Green, White
Black, Bright Green, White
So what do you think of these 20 colour schemes? Do you have a favourite, or is there another option I should have included? Leave your feedback in the comments.
