Brentford's predominant home colours are a red and white striped shirt, black shorts and red or black socks. These have been the club's predominant home colours since the 1925–26 season, bar one season – 1960–61 – when yellow (gold) and blue were used, unsuccessfully.
The colours on entering the Football League, in 1920–21, were white shirts, navy shorts and navy socks. Away kits have varied over the years, with the current colours being a yellow shirt with yellow shorts, both with black detailing, along with yellow socks.
