Colours

Chelsea's first home colours, used from 1905 until c.1912.

Chelsea have always worn blue shirts, although they initially adopted a lighter shade than the current version, and unlike today wore white shorts and dark blue socks. The lighter blue was taken from the racing colours of then club president, Earl Cadogan. The light blue shirts were short-lived, however, and replaced by a royal blue version in around 1912. When Tommy Docherty became manager in the early 1960s he changed the kit again, adding blue shorts (which have remained ever since) and white socks, believing it made the club's colours more distinctive, since no other major side used that combination; this kit was first worn during the 1964–65 season. Since then Chelsea have always worn white socks with their home kit apart from a short spell from 1985 to 1992, when blue socks were reintroduced.
Chelsea's traditional away colours are all yellow or all white with blue trim, but, as with most teams, they have had some more unusual ones. The first away strip consisted of black and white stripes and for one game in the 1960s the team wore Inter Milan-style blue and black stripes, again at Docherty's behest. Other memorable away kits include a mint green strip in the 1980s, a red and white checked one in the early 90s and a graphite and tangerine edition in the mid-1990s.
Chelsea's kit is currently manufactured by Adidas, which is contracted to supply the club's kit from 2006 to 2011. Previously, the kit was manufactured by Umbro (1968–81), Le Coq Sportif (1981–86), The Chelsea Collection (1986–87) and Umbro again (1987–2006). Chelsea's first shirt sponsor was Gulf Air, agreed midway through the 1983–84 season. Following that, the club were sponsored by Grange Farms, Bai Lin Tea and Italian company Simod before a long-term deal was signed with computer manufacturer Commodore International in 1989; Amiga, an off-shoot of Commodore, also appeared on the shirts. Chelsea were subsequently sponsored by Coors beer (1995–97), Autoglass (1997–2001) and Emirates Airline (2001–05). Chelsea's current shirt sponsor is Samsung  who took over the sponsorship from their mobile division in 2007–08.
