Bayern Munich was founded on February 27 1900, and the club's first-ever jersey was light blue inspired by the Bavarian flag. 10 years later, Bayern switched to their trademark colours red and white i... n the form of vertical stripes. During the 1990s, Bayern started to use a lot of blue for their home shirt, which caused an outrage in recent times. Eventually, this led to the club banning the colour on their home shirts back in 2018. Traditionally, Bayern München's alternative jerseys are white and black / navy, but there is a lot more variation nowadays.
