Digital illustration of a mermaid set against a black background. The mermaid has a slender, elongated body with a brown skin tone. Her long, flowing hair is depicted in vibrant, iridescent colors including shades of green, blue, purple, and pink, creating a luminous effect. The hair appears to be floating around her, adding a sense of movement to the image. The mermaid's tail is a gradient of pink hues with a textured, scale-like pattern. Her facial features are delicate and ethereal, with a serene expression. The overall style of the illustration is whimsical and fantastical, with a focus on fluid lines and bright, contrasting colors.
