Frequently asked questions


Is this coloring page prompt generator free?


Yes. It runs in your browser with no sign-up. Copy the prompt into Midjourney, Ideogram, GPT Image or Flux.


How do I stop the AI from adding shading?


Ask for black line art on a white background and add "no shading, no gray, no color". The Midjourney version uses the --no parameter for this.


Can I sell AI coloring books on Amazon KDP?


Many creators do. KDP asks you to disclose AI generated content, and low effort books can be rejected, so check the current KDP guidelines and add real value to every book.


What size should a coloring book page be?


8.5 x 11 in is the most common size. Export at 300 DPI and keep important lines away from the page edges.
