In order to commemorate 100 years of football, the club has launched a series of commemorative activities under the name Real100.
The club is known in Basque as Erreala or the txuri-urdin (meaning "white-blue" in Basque), from their colours: blue with white vertical stripes and white shorts. The club name means Royal Society of Football. A blue quarter on white also appears in the flag of their home town.
Real100 announced a 09/10 kit vote on the official club website, with an option to choose the centenary home shirt here.
