This coloring page contains two beautiful ocean scenes, with mermaids and dolphins swimming together in harmony. The mermaids have gorgeous, long hair cascading down their backs, their colorful tails swishing through the water. The dolphins are playful, their fins cutting through the ripples of the ocean. To color this picture, start by giving the mermaids and dolphins a deep and vibrant blue, bringing out the vibrancy of the sea and its depths. Use a darker shade of blue to define the outlines and highlight their features. Add touches of deep green and a pale pink to give their scales a shimmering effect. Then, bring out the coloring of their hair with a range of vibrant purples, pinks and oranges, ensuring that each mermaid's hair is one of a kind. Finally, lightly add a golden outline to the mermaids' tails and the dolphins' fins, making them stand out in the water.
