That Beautiful Shade Of Blue

Exactly what shade of blue is the water around Grand Bahama Island, anyway?  Of course, the water color changes as you move from deeper water to spots closer to the shoreline.  But as you reach the shallow depths near the beach, the water becomes an inexpressibly beautiful shade of blue.  Is it azure?  Cyan?  Aquamarine?  Turquoise seems to fit best, but then again a word can’t really capture the sunlight glinting on the water, the different shades created as the waves move past, and glimpses of the ocean bottom appear through the crystal clear water.
