This coloring page is bursting with vibrant colors, depicting the vibrant and magical world of mermaids. The foreground is filled with the lively colors of a coral reef, and graceful mermaids dance among them, while an amazing underwater palace looms in the background. To make the picture pop, I would start by coloring the coral reef in shades of pink, orange and purple. I would choose hot pinks and purples for the mermaids, so that their colors contrast against the blues and greens of the sea. For the palace, I'd go for a shimmery silver and gold. With a few touches of magic sparkles here and there, this picture will be a masterpiece!
