This coloring page features two mermaids frolicking in the sea, riding upon the back of two majestic whales. The mermaids have long, flowing hair that is vibrant and colorful, while their tails are a shining silver. Their upper bodies are humanoid and lightly toned, while their fishes' tails are a deep, vibrant blue. To bring this image to life, use bright and fun colors that capture the energy and joy of these magical creatures. Paint in cool blues and greens for the background of the sea. Accentuate each mermaid's eyes with a popping yellow-green, and bring out the highlights of their hair in purple and pink hues. Create details in the whale's body and deep shadows beneath for a more three dimensional look. Finally, add a splash of sparkle to each mermaid's tail to complete the enchanting image.
