🎨 How to color it

Color the shark slate gray with a pale belly, the branching coral in coral pink and seafoam green, and the striped reef fish in lemon yellow with black bands. Use sharp colored pencils for the small fish and coral tips, then switch to smooth marker fills on the shark’s broad body. Add a soft turquoise-to-deep-blue gradient behind the wavy current lines so the shark looks like it is cruising through deeper water.

The story behind this coloring page

Nero Waits for the Blue Bell — Beyond the warm ledge where Nero usually circled, a blue bell pearl was said to ring only when the tide turned twice. Read the full story →

Beyond the warm ledge where Nero usually circled, a blue bell pearl was said to ring only when the tide turned twice. He wanted one for his den roof, so he slipped into the narrow reef pass, past coral that brushed his belly like stiff little fingers. The water tasted of salt and crushed shells. A silent striped fish appeared ahead, flicked its tail once, and vanished behind a fan of white coral.

Nero followed and waited. First came minnows, then bubbles, then nothing but the slow hush of water over stone. His stomach growled; he had missed the easy crab hour back home. “Just one more tide,” he whispered. At last, the striped fish returned with a tiny blue shell in its mouth and tapped it against the coral. Ding. Not a pearl—a warning bell for lost swimmers.

Nero carried no prize home, but he learned the sound by heart. From then on, when foggy silt rolled through the pass, he rang the reef’s secret note with his tail. If you spot the striped fish near the coral, keep your eyes there—the blue bell may be hiding where patience first went ding.
