SokratesWhite and red were officially adopted as national colors in 1831. They are of heraldic origin and derive from the tinctures (colors) of the coats of arms of the two constituent nations of the Polish-Lithuanian Commonwealth, i.e. the White Eagle of Poland and the Pursuer (Lithuanian: Vytis, Polish: Pogoń) of Lithuania, a white knight riding a white horse, both on a red shield. Prior to that, Polish soldiers wore cockades of various color combinations. The national flag was officially adopted in 1919.
shortly white is colour of king (btw white was colour of frenh kings either) and the red was a colour of grand duke of lithuania.
