 In any case the oldest documented Savoy flags, dating back to 1589, have the colors red, white (or the colors of the coat of arms of the dynasty) and blue.The latter color acquired over time prevalence until it became the Italian national color.Referring to the Marian cult, the ribbons of the Order of the Annunciation (the greatest Savoyard knight sign, transplanted also in the kingdom of Italy), were blue; blues, also in the Republican era, are also the ribbons of the decorations of military valor (gold, silver, bronze medal and the war cross).
