🎨 How to color it

Layer coral, sandy beige, and pearl pink through the large seashell, then set the curling wave in teal and deep navy with a golden mandala sun above it. Use sharp colored pencils for the tiny spirals, scallops, dots, and petal shapes, working one band of pattern at a time to keep the details crisp. For a secret summer glow, blend the sun from lemon yellow at the center to orange at the points, then echo a few warm highlights inside the shell’s spiral chambers.

The bold black ribs of the seashell look decorative, yet they divide the shell like a map to something hidden. Can you trace the smallest dotted path along the sand before it slips under the wave? Nora has challenged herself to color only the patterns that point toward the secret: three spirals on the shell, one curling crest in the wave, and the tiny circle tucked inside the sun. If those clues match, the tide has left her a message.
