At the center of the page, the mermaid stands out with her flowing hair and decorated tail. She clutches a cluster of strings tied to balloons shaped like conch shells and starfish. To her side, an open treasure chest spills over with gold coins, suggesting a hidden stash of pirate gold found on the seafloor. This focal point is surrounded by a variety of textures and shapes that make the scene feel full and active.

Look closer to see a friendly seahorse and a small fish swimming nearby, adding life to the scene. The seabed is covered in detailed coral, waving seaweed, and small starfish resting on the sand. Tiny bubbles drift upward, filling the space between the marine life and the festive balloons, creating a sense of movement throughout the entire underwater kingdom.

For the mermaid's tail, you might try using a shimmering green or a vibrant purple to make her stand out against the blue water. The seashell balloons look wonderful in soft pastels like lavender, mint, or peach. Since there is a treasure chest, using a bright yellow or a metallic gold crayon for the coins will make the treasure look like it is truly glowing under the sea.

The surrounding coral and seaweed provide a great chance to use deep reds, oranges, and various shades of green. If you want to create a sense of depth, try coloring the water in the background a lighter blue near the top and a darker navy towards the bottom. This helps the cheerful characters and the bright balloons pop right off the page while giving the ocean a realistic, layered appearance.
