The Seattle Seahawks unveiled their name and original logos to the world on June 17, 1975; at the time, the name 'Seahawks' was described by GM John Thompson as "a tough, fish-eating bird". The name was selected by the team from a list of 1741 names submitted by fans, 150 different people submitted the "Seahawks" name. Their logo is based off of the Seattle-area Native American culture.
The Seahawks have used a variation of their original mark throughout their entire franchise history, making tweaks to the design to modernize when approrpiate. A grey helmet was used for the first 26 seasons and was intended to be used alongside the modern blue lid as a road-only helmet beginning in 2002, however the NFL quickly ended that plan. A fan vote was held to choose which colour the team would use full-time with blue ultimately prevailing.
