How we make our pages

We want you to know exactly how each picture is made.

Mandalas and patterns

Mandalas are drawn by our own code from a few rules: how many folds, which ring shapes, how thick the lines are. Because the code knows every ring, matching parts of the mandala get the same number, so the pattern stays symmetric as you color.

Cute animals and scenes

The line art is AI-assisted and then selected and cleaned. To choose the colors, an AI image model colors a copy of the line art; our code then reads the main color inside each area and maps it to a short, named palette. The finished answer sheet is drawn from that mapping, not from the AI image, so the numbers, the key and the answer always agree.

Numbers, PDFs and the online studio

One file per picture holds the areas, the number of each area and where its label goes. The PDF, the preview images and the online studio are all built from that same file. Areas too small to hold a readable number are filled in for you.

What a person checks

Before a picture is published, a person looks at the numbered sheet, the answer and the PDF, and checks that the colors make sense. We do not claim every page was test-printed by hand. If you find a mistake, please report it.
