Using a brown Pocillopora meandrina as a test case, coral coloration was visually assayed after exposure of this SPS to focused light from either blue, red, green, yellow, or ultraviolet LED's over a period of greater than 7 weeks. The coral section irradiated by the blue LED turned from brown to pink, whereas the other colored lights either had no effect, or promoted coral bleaching. This limited investigation led to some intriguing speculation about the connection between growth light and coral color, and it sets the stage for the more extensive studies described below.
