Written by ThumbPrompt Pro Team
As AI art creators and Amazon KDP publishers, we've tested thousands of prompts to find the exact parameters needed to produce flawless, commercial-ready coloring book interiors.
The demand for coloring books has never been higher. What was once just a fun activity for children has evolved into a massive mindfulness and relaxation niche for adults. If you are looking to tap into a highly profitable passive income stream, selling coloring books on platforms like Amazon KDP (Kindle Direct Publishing) or offering printable downloads on Etsy is an excellent business model.
However, paying illustrators for a 50-page book can cost thousands of dollars. Enter Midjourney v6. With the right commands, you can generate stunning, clean, and intricate line art in seconds.
The challenge? If you just type "a coloring page of a dog," you'll often end up with messy shading, grayscale gradients, or weird artifacts that ruin the coloring experience. In this guide, we are sharing our curated list of the 50+ best Midjourney prompts for coloring pages, guaranteeing clean outlines and commercial readiness.

How to Clean Up AI Line Art for Amazon KDP
Even with the absolute best prompts, AI can sometimes leave faint gray smudges or imperfect lines. If you upload these directly to KDP, your book might be rejected for quality issues, or customers will leave bad reviews.
The Post-Processing Workflow:
- Upscale: Use an AI upscaler to increase the image size (e.g., 300 DPI for an 8.5x11 inch page).
- Vectorize (Optional but recommended): Use a tool like Adobe Illustrator (Image Trace) or a free online vectorizer like Vectorizer.ai to convert your PNG to an SVG. This makes the lines mathematically perfect and infinitely scalable.
- Levels Adjustment: If you are using Photoshop, open the image and adjust the "Levels." Drag the black slider slightly to the right, and the white slider to the left. This crushes any hidden gray pixels into solid black or pure white, ensuring crisp KDP printing.
