Blue has a wide range of meanings in different cultures. In Greece, the color blue is believed to ward off “the evil eye.” In Aztec culture, blue symbolized sacrifice.Due to the water streams, the coral reefs and the sandbanks that crisscross the ocean like a huge underwater dunescape, the variety of different shades of blue is unique in the remote archipelagos of the Indian Ocean. From ultramarine to cyan, from turquoise to azure, from indigo to sapphire blue - the subtle nuances and gradations shape the character of this underwater landscape. Unfortunately, these fragile systems are in real danger due to rising water temperatures caused by global warming.
