Alpha Chi Omega's colors of scarlet red and olive green were chosen to commemorate the fraternity's fall founding. The fraternity's official symbol is a three-stringed lyre and the official flower is a red carnation, which exemplifies the fraternity's colors. There is no official stone. The badge (pin) worn by initiated members is in the shape of a lyre, typically featuring pearls and the fraternity's Greek letters on the crossbar. Alpha Chi Omega chose the lyre to be their official symbol since it was the first instrument played by the Gods on Mount Olympus. Although Alpha Chi Omega no longer is strictly a musical sorority, they are still connected to their musical heritage through their symbol of the lyre.
