About

A quiet color by number book that opens in your browser.

What it is

Color by Number Online is a collection of pictures you fill in shape by shape: pick a numbered color, tap its shapes, and the finished picture comes up piece by piece. There are flowers, animals, landscapes, food, seasonal scenes and cozy rooms, in Easy, Medium and Hard. It is free to use, needs no account and has nothing to install.

How the pictures are made

The 40 pictures here are AI-generated. Each starts as a flat illustration made with an image model, then our tools check that it has the right number of shapes for its level and turn it into the outlines, numbers and palette you paint with. Every picture you see was reviewed before it went on the site. We keep out real people, brands, logos and well-known characters.

The daily picture is worked out from the date on your device. It steps through a shuffled order so that every picture appears once before any repeats, and a new order begins when that round is done.

Your progress

Your paint and your finished pictures are stored in your own browser, on your device. They are not tied to an account and do not carry over to another phone or computer unless you move them with an export code from the gallery. See the privacy page for details, or how to play if you are just getting started.

Color by Number Online is a Cain Brands site.
