Stable Diffusion Prompt for Coloring Book

Coloring books are a fun and creative way for both children and adults to relax and express their artistic abilities. With recent advances in AI image generation technology like Stable Diffusion, it is now possible to automatically generate custom coloring book pages tailored to specific interests or themes.

In this article, I will provide examples of effective Stable Diffusion prompts for generating clean, crisp coloring book pages on various topics. I have over 5 years of experience experimenting with AI art generators and have discovered some best practices for crafting prompts that yield high-quality results.

Effective Prompts for Coloring Books

When generating coloring book pages with Stable Diffusion, there are a few key elements to include in your prompt:

Specify the Content

Clearly describe the main subject you want depicted in the image. For example:

  • A cute baby owl with large eyes
  • A girl painting at an easel
  • An elephant walking through a forest

Style Details

Use descriptive terms to indicate the visual style for a coloring book:

  • Clean line art
  • Minimalistic
  • Flat colors
  • High contrast
  • No shading or blending


Guide the composition so the subject stands out clearly:

  • Centered composition
  • Subject taking up most of the frame
  • Simple background or no background


Emphasize quality so lines are smooth and solid:

  • Crisp lines
  • Sharp focus
  • High resolution
  • No artifacts or noise

Here is an example prompt putting all those elements together:

A centered composition of a cute baby owl with large eyes, clean line art, flat colors, high contrast, no background, crisp lines, sharp focus, high resolution

Advanced Prompting Techniques

There are also some more advanced techniques you can use to further improve your coloring book prompts:

Enhance Lines

Use terms that emphasize bold, defined lines:

  • Strong lines
