This beautiful mermaid is contentedly swimming in her underwater world. Her long blonde hair streams behind her, swaying with the gentle currents. Her tail is decorated with shimmering scales in shades of purple, blue, and pink, enhanced by swirls of glittery sparkles. To emphasize the motion of the water and surrounding reef, the artist has used delicately curling lines to evoke the flow of the current. To capture the colors of the ocean depths, use shades of teal, turquoise, and cobalt blue for the background. You can explore contrasts between the blue background and the colors of the mermaid's tail, using shades of lavender and navy to replicate the play of light on her scales and bringing out the sparkles of her rainbow-hued tail.
