AI Coloring Page Generator
A coloring page is a very specific object: pure black outlines on white, closed shapes, no shading, and lines thick enough that a child's crayon has somewhere to go. Getting one out of an image model is entirely a matter of saying so.
The failure mode is grey. Ask for "a line drawing" and you get a sketch with soft pencil tone, which prints as mud and cannot be coloured in. The words that fix it are "pure black outlines on pure white, no shading, no grey, closed shapes". Then set the difficulty deliberately: thick simple lines and big areas for a small child, finer detail and more of it for an adult page.

Questions
- Will it print properly on A4?
- Generate at a taller shape and a higher quality tier and it prints clean. Pure black on white survives printing better than anything else.
- Can I make a page from a photo of my own child or pet?
- Yes — upload it and ask for the coloring page treatment. It keeps the pose and simplifies the rest.
- Can I sell a coloring book made this way?
- The images are yours commercially. The usual care applies to subjects that belong to somebody else.
