Prior to sponsorships, Brabham raced in turquoise with a gold band running across the car. This later changed to green and gold, the racing colours of Australia. A Brabham car was the first F1 car painted in the livery of a team's sponsor when Team Gunston as a privateer team entered a private Brabham car at the 1968 South African Grand Prix. In 1975 and 1976, Brabham received sponsorship from Martini; in 1976 the color scheme changed from white to red with light blue trim. The primary sponsor changed to Parmalat in 1978, with the cars retaining a variant of the same red and blue colors. With the team's switch to BMW engines in 1982, the new livery consisted of a clean dark blue and white with a stylized BMW "kidney grille" on the nose. This scheme was retained throughout the BMW years, even through a sponsorship change to Olivetti in 1984, until 1989. (This unusual representation of the engine supplier, specifically BMW, in the color scheme was revived by Williams when they debuted their own BMW cars in 2000.) In 1989, Brabham signed with Bioptron, a brand of Zepter International, which continued until the team was bought by Middlebridge Group. Since then, it was sponsored by many Japanese companies like Garage Italiya, a company that imports Italian cars in Japan, Autobacs, Nippon Shinpan, and Mitsukoshi. In its final season Brabham raced in blue and pink livery of the Japanese metal group Seikima-II.
