Mermaid Coloring Book Prompts for Kids, Teens & Adults

Mermaid coloring books combine two favourite themes, magic and the ocean, and they sell strongly as gifts for girls from preschool to the tween years. Detailed mermaids with flowing hair and shell-covered tails are also a popular adult coloring niche. These mermaid coloring book prompts cover a sweet book for little kids, a full undersea kingdom adventure, and an ornate mermaid fantasy book for teens and adults, all with original characters.

Tips for making a mermaid coloring book

  • Keep every mermaid original; avoid famous red-haired film mermaids and their sidekicks so the book is safe to sell.
  • Add sea friends (turtles, dolphins, octopuses) to almost every page; they make mermaid books far more varied than solo portraits.
  • Include merboys and mermaids of different looks, which broadens the gift audience.
