The surface is calm, a black mirror under the stars, and then the lights cut through—a narrow cone of electric blue that teases color from the reef like a signal. Divers move slowly off the shore at The Hole in the Wall, visors down, masks dimmed by a yellow filter so small fluorescent polyps and hidden critters leap into view.
