A turquoise coral reef with pink and orange coral branches, striped tropical fish and a large white and orange koi-like fish drifting near the seabed. The dark, blocky coral cluster in the middle and the stacked rock ledges on either side carry the dense dark modules, while the finder squares are hidden among the coral and stone. Pale sand, bright water and light rays supply the light modules, so the dark shapes keep strong contrast against them. Small fish scattered through the upper water add fine detail without crowding the pattern.
