Originally, the club wore yellow and blue chequered shirts in honour of the city's traditional colours, which date back to 1545 when the Duchy of Parma was established, but white shirts with a black cross on the chest were introduced after the First World War, drawing inspiration from Juventus' colours, following a name change. White continued to be worn as the main colour of the home kits for much of the remainder of the century, although often complemented with yellow, blue or both, rather than black. The club did, however, experiment in the 1950s with blue shirts and blue and yellow striped shirts. The cross shirts were restored and worn until bankruptcy in 1968, when white shirts with off-centre blue and yellow vertical bands were worn, but the cross returned from 1970 until 1983 when a yellow and blue-sleeved white shirt was introduced and used for 8 years.
