"The flag background is blue, reflecting the Atlantic Ocean and Caribbean Sea, which surround the island. In the centre is a distinctive emblem that includes white and black to indicate harmony between the races living on Saint Lucia; its yellow triangle represents the constant sunshine that the tropical island enjoys and that serves to encourage the tourist industry, and its black triangle symbolizes the topographic features known as the Pitons, ancient volcanic cones found in the southwest of Saint Lucia. At the time of independence on February 22, 1979, the shade of blue and the relative sizes of the yellow and black triangles in the flag were slightly altered." (source: britannica)
