Rainbow Friends Coloring Book

Rainbow Friends Coloring Book lets you jump straight into coloring creepy-cute rainbow monsters and blue heroes from the first screen. Open a page, pick a Rainbow Friend monster or a Blue Hero pose, and turn the black-and-white drawing into your own version with any colors you like. The pages keep the original monster shapes, so no matter what palette you try, the characters still look recognizable from the Rainbow Monsters world.

How to play?

Tap a picture to open it, then select pencils, brushes, crayons, or stickers from the toolbar. Fill big areas with quick taps, or drag the brush for smaller parts like eyes, teeth, and outlines. Mix light and dark tones to make shadows on your rainbow monster blue pages, which helps the character stand out clearly on the screen. Follow the sample colors if you want the classic Rainbow Friends style, or ignore it and design your own monster colors. Use different brush sizes to keep lines clean around faces and hands. When a drawing looks finished, save it, then try another character so the whole collection slowly fills with your custom versions.

Practice copying simple shapes directly from the pictures to learn how to draw Rainbow Friends from scratch on paper later. Load up Rainbow Friends Coloring Book, pick a monster, and start filling the gallery with your personal rainbow squad.
