British Racing Green is the official international racecar color of Britain.

In the days of the Goron Bennett cup where every component of a car had to be produced in the country in was manufactured in as well as the driver being of that nationality. The race was hosted in the country of the previous year's winner. When Selwyn Edge won the 1902 race for Britain it was decided that the 1903 race would be held in Ireland. As a mark of respect for their hosts the British cars were painted green and this has remained the traditional colour for British racing cars to this day.

William Grover-Williams, driving for Britain, won the very first Monaco Grand Prix in a dark green Bugatti. This colour became known as British Racing Green and was regarded as the "official" colour between 1962 and 1973, when British teams dominated Formula One and won twelve World Championships.

Officially Deep Brunswick Green (British Standard Colour Code #BS 381 C), British Racing Green can range from dark green to nearly black.

With the many successes of the British racing teams through the years, British Racing Green became a popular paint choice for British sports and luxury cars.
