Originally, the buses of one of Valley Metro's predecessors, Phoenix Transit System, were painted with an orange and pink stripe, and a logo on the sides, rear and front, featuring a character known as "Tico", which was a sun wearing sunglasses, and a sombrero. In the late 1980s, this logo disappeared and buses were simply labeled "City of Phoenix Transit System". In 1993–1994, the RPTA changed the colors to a green and purple color scheme (which many vehicles still have), with a green stripe and a large purple "V" on the passenger's side, and the reverse on the driver's side.
