A Sounder is a person from Puget Sound, the body of water Seattle sits on. The name was picked for Seattle's first professional soccer team in the NASL in 1974, carried through the USL-era club from 1994, and written in by fans in a 2008 naming vote before the MLS club adopted it.

1974: the NASL Sounders

Seattle's North American Soccer League franchise launched in 1974 and needed a name that said Seattle without saying Seattle. Puget Sound was the obvious hook. The Sounders played at Memorial Stadium and then the Kingdome, drew big crowds for the era, and reached the Soccer Bowl in 1977 and 1982 before the league folded in 1983.

1994 to 2008: the USL Sounders

A second-division Seattle Sounders returned in 1994 in the A-League, later the USL First Division. That club won titles in 1995, 1996, 2005, and 2007 and kept the name alive for the fans who would fill the stadium in 2009.

2008: the vote

When Seattle was awarded an MLS expansion team, ownership leaned toward a fresh identity at first. The club put three names to a public vote, Seattle FC, Seattle Republic, and Seattle Alliance, and allowed write-ins. About half of the responses wrote in "Sounders" in some form, and the club announced Seattle Sounders FC in April 2008.

The Alliance idea stuck around in another form. It became the Sounders FC Alliance, the membership organization that gives season-ticket holders a vote on retaining the general manager.

The colors

Rave Green is the primary color, chosen to stand apart from the Seahawks' navy and the Mariners' teal. Sounder Blue is the secondary. Cascade Shale is the grey.
