Colours and uniforms thumb|Sébastien Grosjean takes a shot on Court 18 during the 2004 Championships. Dark green and purple are the traditional Wimbledon colours. However, all tennis players participating in the tournament are required to wear all-white or at least almost all-white clothing, a long-time tradition at Wimbledon. This rule was put in place in 1963, when the tournament's first dress code was enforced. Wearing white clothing with some colour accents is also acceptable, provided the colour scheme is not that of an identifiable commercial brand logo (the outfitter's brand logo being the sole exception). Controversy followed Martina Navratilova's wearing branding for "Kim" cigarettes in 1982. In 2023 rules first allowed all female players, included but not limited to in the girls’ singles junior event, to wear non-white underwear; the new rule allows "solid, mid/dark-coloured undershorts, provided they are no longer than their shorts or skirt". Green clothing was worn by the chair umpire, linesmen, ball boys and ball girls until the 2005 Championships; however, beginning with the 2006 Championships, officials, ball boys and ball girls were dressed in new navy blue- and cream-coloured uniforms from American designer Ralph Lauren.
