England's FA required clubs to have a spare white kit in case of a colour clash, in which case it was the home team who had to change.

In 1921 that flipped and the "away kit" was born. Squad numbers were also introduced in the 1920s, along with separate kits for goalkeepers. https://twitter.com/culturaltutor/status/1628293996945543173/photo/1 (source: https://twitter.com/culturaltutor/status/1628293996945543173)
