The official team colours are Sounder Blue, representing the waters of the Puget Sound; Rave Green, representing the forests of the Pacific Northwest; and Cascade Shale, representing the Cascade Range to the east of Seattle.

Xbox 360 also will be featured as the presenting sponsor of the Sounders FC annual international tour and will gain entitlement to the team’s playing surface, "The Xbox Pitch at Qwest Field". Xbox 360 will be recognized as the official and exclusive video game console of Major League Soccer.
