What is Happy Color®: Coloring Book

Happy Color®: Coloring Book is a mobile “color by number” app developed by X‑Flow (Pixel Art) that transforms digital coloring into a relaxing, mindful pastime. Users choose from thousands of pre‑drawn illustrations across a wide array of categories — nature, animals, mandalas, Disney/Marvel, architecture, fantasy, fashion, and more — then fill in numbered regions with the corresponding colors. The process is intuitive: tap a color, tap all areas labeled with its number, and watch the picture gradually come alive. The app often provides daily new designs, occasional events, achievements, and a social/community sharing aspect. Its appeal lies in combining simple mechanics with visual satisfaction and stress relief.
