These colors... on the bike? In Christina's cabin? The shield on the wall? In the boat from her childhood?

According to legend, the arms of Aragón were origially plain gold: in heraldic terms "Or plain". Geoffroy le Velu, king of Aragón, was mortally wounded fighting on the side of Charles le Chauve against the Normans. Charles, to show his gratitude for Geoffroy's bravery, dipped his fingers in his blood and smeared them onto the shield, making the present arms, in heraldic terms "Or four pallets gules".
