Colouring book line-art samples
Three 8.5×8.5 inch colouring pages drawn as vector shapes in code, at a consistent 3.2 pt line weight.
The goal
Show the style, line weight, margins and page format of a planned children’s colouring book before any final artwork is made.
What was built
- Three cute animal characters drawn as vector shapes
- A vector PDF plus 300 DPI PNG exports
- A cover layout guide for the designer
What we learned
Drawing in code produced clean, consistent outlines that print well, and made the line weight easy to standardise across pages.
Limits, stated plainly
Style samples only. The full book is not finished or on sale. If later pages use AI-generated art, it will be declared to Amazon.

Tell me what you need done
Describe the job in a few lines. You get a fixed-price scope, or an honest “not for me”.
Is this a client project?
No. DEMO – not a client project. It was built and tested with fictional data.
Are the numbers real?
Yes: they come from the actual tests and files of this build. Anything simulated is labelled as simulated.
