The flag of Barbados is very simple but very elegant.
The left blue stripe represents the sky and the yellow/gold stripe symbolizes the sand. The right blue stripe represents the sea. The trident in the middle of the Barbados flag represents Barbados independence from the British, with each point of the trident representing the three principles of democracy which are government of, for and by the Barbados people. The trident is also the symbol of Neptune, god of the sea in greek mythology; as such it also denotes the very important relationship between Barbados and the Sea.
