During World War II, in Italy, all national teams used white clothes to match colors, and even used all-black colors (insinuating Mussolini's dark rule). Although Mussolini was unhappy, he couldn't suppress the people by force based on the color of clothes, so he proposed to use Azzurro, the national color of Savaja in history, as a national symbol and continue the tradition to this day.

Cyan, Azzurro, Italy, is the national color of Italy. Widely used in official activities and military parade. Cyan comes from Savoy Blue. The Xavier family used to be the royal family of Italy. Since 1360, this color has become the official color of the savoia family and the national flag of the Italian Principality of savoia. Later, the Principality of savoia unified Milan, Venice, Turin, Genoa and the whole kingdom of Sicily. After the unification of the Italian kingdom, the national flag with green, white and red vertical stripes and the royal emblem of savoia was taken as the national flag, and blue was decided as the national color and continues to this day.
