This beautiful coloring page features three mermaids who are comfortably holding hands in a circle. Each mermaid has an incredible long, flowing hairstyle and a colorful tail, with one being blue, one being green, and one being purple. Their look is complete with regal crowns and sparkling jewelry. To make this scene shine, I would start by adding some color and texture to the mermaids' tails. I'd fill the blue tail with a deep navy shade and add fun highlights of brighter blues and greens. For the green tail, I'd use a combination of vibrant, grassy hues with shimmery highlights. The purple tail could be filled with a royal violet and then sprinkled with lighter shades of lavender. The jewelry and crowns can be filled with glittery gold, sparkling silver, and hints of pink and blue, which will give the picture an extra-magical finish.
