Colours

Arsenal's original home colours. The team wore a similar kit (but with redcurrant socks) during the 2005–06 season.

For much of Arsenal's history, their home colours have been bright red shirts with white sleeves and white shorts, though this has not always been the case. The choice of red is in recognition of a charitable donation from Nottingham Forest, soon after Arsenal's foundation in 1886. Two of Dial Square's founding members, Fred Beardsley and Morris Bates, were former Forest players who had moved to Woolwich for work. As they put together the first team in the area, no kit could be found, so Beardsley and Bates wrote home for help and received a set of kit and a ball. The shirt was redcurrant, a dark shade of red, and was worn with white shorts and blue socks.
In 1933, Herbert Chapman, wanting his players to be more distinctly dressed, updated the kit, adding white sleeves and changing the shade to a brighter pillar box red. Two possibilities have been suggested for the origin of the white sleeves. One story reports that Chapman noticed a supporter in the stands wearing a red sleeveless sweater over a white shirt; another was that he was inspired by a similar outfit worn by the cartoonist Tom Webster, with whom Chapman played golf.

Regardless of which story is true, the red and white shirts have come to define Arsenal and the team have worn the combination ever since, aside from two seasons. The first was 1966–67, when Arsenal wore all-red shirts; this proved unpopular and the white sleeves returned the following season. The second was 2005–06, the last season that Arsenal played at Highbury, when the team wore commemorative redcurrant shirts similar to those worn in 1913, their first season in the stadium; the club reverted to their normal colours at the start of the next season. In the 2008–09 season, Arsenal replaced the traditional all-white sleeves with red sleeves with a broad white stripe.
Arsenal's home colours have been the inspiration for at least three other clubs. In 1909, Sparta Prague adopted a dark red kit like the one Arsenal wore at the time; in 1938, Hibernian adopted the design of the Arsenal shirt sleeves in their own green and white strip. In 1920, Sporting Clube de Braga's manager returned from a game at Highbury and changed his team's green kit to a duplicate of Arsenal's red with white sleeves and shorts, giving rise to the team's nickname of Os Arsenalistas. These teams still wear these designs to this day.
For many years Arsenal's away colours were white shirts and either black or white shorts. Since the 1969–70 season, they have worn yellow and blue, but there have been exceptions. They wore a green and navy away kit in 1982–83, and since the early 1990s and the advent of the lucrative replica kit market, the away colours have been changed regularly. During this period the designs have been either two-tone blue designs, or variations on the traditional yellow and blue, such as the metallic gold and navy strip used in the 2001–02 season, and the yellow and dark grey used from 2005 to 2007. As of 2009, the away kit is changed every season, and the outgoing away kit becomes the third-choice kit if a new home kit is being introduced in the same year.
Arsenal's shirts have been made by manufacturers including Bukta (from the 1930s until the early 1970s), Umbro (from the 1970s until 1986), Adidas (1986–1994), and Nike (since 1994). Like those of most other major football clubs, Arsenal's shirts have featured sponsors' logos since the 1980s; sponsors include JVC (1982–1999), Sega (1999–2002), O2 (2002–2006), and Emirates (from 2006)
