To make a coloring book with AI, choose a precise theme and audience (kids or adults), generate black line art on white with a strict prompt, clean up every page (closed lines, no grey, no stray text), set it to print size at 300 DPI, then disclose the AI-generated images when you publish on KDP. Here is the full method, with prompts and the checks that prevent bad reviews.

Step 1: a precise theme and audience
"Animals" is too broad. "Funny dinosaurs for kids aged 4 to 6" or "ocean mandalas for adults" are niches. The audience decides everything: line weight, level of detail, size of the areas to color. Our guide to kids' coloring books on KDP covers these choices.
| Audience | Lines | Details |
|---|---|---|
| Kids 3-6 | Very thick | Large areas, one subject |
| Kids 7-12 | Thick | Subject and a simple background |
| Adults | Fine to medium | Rich patterns, mandalas, scenes |
Step 2: a line art prompt
The prompt must rule out everything that gets in the way of coloring:
"Coloring book page for kids, a cute baby dinosaur playing with a ball, thick clean black outlines, pure white background, no shading, no gray, no color, no text, simple shapes, large areas to color, full page composition."
For adults: "Adult coloring page, intricate ocean mandala with fish and shells, fine clean black line art, pure white background, no shading, no gray, symmetrical, no text."
Keep a list of the words that work for your style ("thick outlines", "no shading") and reuse it for the whole book: that is the key to consistency.
Step 3: sort and clean every page
AI often produces flaws a child will notice:
- Grey or shaded areas: remove them, they print dirty.
- Open lines: areas must be clearly closed.
- Absurd details: extra legs, merged objects.
- Pseudo-text: warped letters to erase.
Convert each image to pure black and white (threshold) in an editing app, then fix by hand. For perfectly crisp files, vectorizing works very well on line art.
Step 4: prepare the book
- Trim size: 8.5 × 11 inches is the most common for coloring books.
- Resolution: 300 DPI, which is 2550 × 3300 pixels for a full page without bleed.
- Single-sided pages: print drawings on one side only, so markers do not bleed through and ruin the next drawing.
- Bonus pages: a "This book belongs to" page and a color test page.
Step 5: publish and disclose
When you publish on KDP, state that the book contains AI-generated images. It is mandatory, even if you retouched the drawings. The other steps (categories, price, cover) are in our guide on how to publish a book on Amazon KDP.
Frequently asked questions
Can I sell an AI-made coloring book on Amazon?
Yes, as long as you disclose the AI-generated images when publishing and follow KDP's content guidelines.
What resolution for a KDP coloring page?
300 DPI. For an 8.5 × 11 inch page without bleed, that is 2550 × 3300 pixels.
How do I keep a consistent style throughout the book?
Use the same base prompt for every page, changing only the subject, and be strict about discarding images that drift from the style.
In short
AI hugely speeds up creating the drawings, but a good coloring book is made in the sorting and cleanup. Pick a precise niche, keep your prompt constant, check every page the way a child would, and disclose your AI use honestly on KDP.
