Real Madrid jerseys are primarily white for historical and cultural reasons. The club adopted the white colour early in its history, around the 1920s, as a representation of purity and elegance. The all-white kit became synonymous with Real Madrid's identity and has remained a defining feature of their jerseys ever since. The white colour is also associated with the club's nickname, "Los Blancos" (The Whites), further emphasizing the iconic nature of the white jerseys.
