🎨 How to color it

Layer the turtle’s shell in jade green, deep teal, and pearl white, then color the coral branches warm coral pink, the tiny fish golden yellow, and the corner waves soft turquoise. Use sharp pencils and work from the center flower outward, because the shell’s petals, scallops, and dotted borders are packed with narrow spaces. For a secret-glow effect, make the shell’s central flower slightly warmer than the outer rings, as if moonlight is caught under the pattern.

The story behind this coloring page

Why Shells Keep Moonflowers — Under the midnight grotto, Vesper carried a dull pearl button beneath her tongue, though every collector in the reef had called it worthless. Read the full story →

Under the midnight grotto, Vesper carried a dull pearl button beneath her tongue, though every collector in the reef had called it worthless. She wanted to place it in the black hollow at the old coral gate before the tide turned; without a light there, the small night fish would scatter into the cold trench. The water tasted of iron and crushed shells, and the gate made no sound except a slow, waiting click.

No one followed. That was the point. Vesper pressed the button into the hollow and backed away, giving up the only thing left from the turtle who had raised her. The pearl did not shine like treasure. It opened like a pale flower, petal by petal, and thin silver lines ran across Vesper’s shell, curling into patterns where there had been plain green before.

By morning, the fish found their way home, and the gate had gone quiet again. Vesper told no one what she had spent. Ever since, sea turtles have carried moonflowers on their shells, so lost light always has somewhere generous to hide.
