The club takes its nickname, "The Pilgrims", from an English religious group that left Plymouth for the New World in 1620. The club crest features the "Mayflower", the ship that carried the pilgrims to Massachusetts. The club has predominantly played in green and white throughout their history, with a few exceptions in the late 1960s and early 1970s when white was the colour of choice. A darker shade of green, described (by some) as "Argyle green", was adopted in the 2001–02 season, and has been used ever since. The city of Plymouth is the largest in England never to have hosted top-flight football. They are the most southerly and westerly League club in England and the only professional club named Argyle.
