🎨 How to color it

Color the mermaid unicorn’s mane in lavender and aqua, her scaly tail in teal, the rainbows in coral, yellow, and sky blue, and the seahorses in soft orange. Use sharp colored pencils for the small tail scales and star marks, then switch to broader strokes for the wide rainbow bands and foamy wave curls. Try making the horn a spiral gradient from pearly white to gold so it feels like it is catching secret underwater light.

The story behind this coloring page

The Game of Hidden Rainbows — Under the cloudbank shallows, where foam smelled like salt and rain, Thalia tapped her horn against a bubble and invented a game called Find-the-Color. Read the full story →

Under the cloudbank shallows, where foam smelled like salt and rain, Thalia tapped her horn against a bubble and invented a game called Find-the-Color. She wanted to hide seven bright trails where no one could guess them, not even the nosy seahorses. Each trail curved behind a shell, a star, or a swirl of seaweed, and the water hummed when she finished.

Then the sea grew dim. Tiny sea sparks, no bigger than fish scales, drifted in circles because the clouds had swallowed their path home. Thalia looked at her hidden colors. If she kept them secret, she would win her own game. Instead, she nudged each color loose with her horn. “Follow these,” she whispered, and the trails arched through the gray water.

The sparks found their way, chiming like little bells, but nobody saw Thalia tuck her empty horn beneath her mane. By morning, every stormy shallows had bright curved paths after rain, because generous colors remember where they were given. Next time you notice the rainbow bands around Thalia, see if you can find the secret game she never asked to win.
