In October 2025, I spent $47 on AI tools and listed 12 coloring book titles on Amazon KDP. Thirty days later, those listings had generated $847 in royalty income — with zero prior publishing experience and no design degree.
This post breaks down exactly what I did, which tools I used, and what I’d do differently if I started today. No fluff, no “get rich quick” promises — just the actual steps and numbers.

Why Coloring Books?
Amazon KDP (Kindle Direct Publishing) has been a side hustle channel for print-on-demand books since 2014. What makes coloring books particularly suited to AI creation?
High demand, predictable seasons. Coloring books sell consistently year-round but spike in Q4 (October–December) as holiday gifts. Teachers buy them year-round for classroom use.
Visual products + AI = natural fit. Unlike text-heavy books, coloring books rely on line art — exactly the kind of artwork that Midjourney and similar tools generate quickly and affordably.
Low production cost. KDP prints on demand. You don’t pay anything upfront. Amazon takes a royalty cut, but you keep 35–70% of the list price depending on pricing and printing costs.
Keyword search is straightforward. Parents and teachers search for specific themes: “dinosaur coloring book for kids ages 4-8” beats generic terms. This makes organic discovery via Amazon’s search algorithm achievable without a massive marketing budget.
According to a 2025 report from self-publishing consultant Self Publishing Formula, coloring books consistently rank among the top 5 most profitable KDP categories for new publishers, with average monthly royalties 3–4x higher than generic fiction.
The AI Tool Stack I Used
| Tool | Purpose | Cost |
|---|---|---|
| Midjourney | Generate high-quality line art for coloring pages | $10/month (Standard plan) |
| ChatGPT Plus | Generate titles, descriptions, keyword research, interior page text | $20/month |
| Canva (Free) | Layout and compile PDF interiors, design covers | $0 |
| Amazon KDP | Publish and manage listings | $0 |
| Calibre (Free) | Convert files to Amazon’s required format | $0 |
Total tool investment in month 1: $47 (Midjourney $10 + ChatGPT $20, prorated for half a month, plus $12 in Amazon KDP select enrollment — though I later learned you can avoid this fee).
One important note: always review AI-generated artwork before publishing. Midjourney’s line art sometimes produces images that are too complex for coloring (thin lines, tiny details, inconsistent line weight). Test print a page before listing to make sure it actually works with real markers or crayons.
Step-by-Step: From Idea to Listed Product
Step 1: Niche Research (Week 1)
Before creating anything, I spent 3 evenings researching what was actually selling on Amazon.
What I did:
1. Searched Amazon for “coloring book for kids ages 4-8” and noted the top 20 titles
2. Used ChatGPT to analyze patterns in their titles, page counts (most are 50–100 pages), and price points ($6.99–$12.99)
3. Identified underserved niches: specific animal types (axolotl, capybara, red panda), professions (veterinarian, marine biologist), and activity-based themes (mandalas for adults, I Spy style for kids)
4. Cross-referenced Google Trends to confirm seasonal interest patterns
Key finding: Niche themes (e.g., “Axolotl Coloring Book for Kids Ages 4-8”) consistently outperformed generic titles (“Fun Coloring Book”). Long-tail keywords in the title directly correlated with better search ranking.
Step 2: Generate the Artwork (Week 1–2)
With Midjourney, I used a prompt structure like this:
a black and white coloring page, clean bold lines, simple design, suitable for children ages 4-8, white background, no shading, no gray tones --v 6.1 --s 200
Each generation takes about 30 seconds and produces 4 image variations. I’d regenerate 2–3 times per spread until I got something printable.
Critical tip: Tell Midjourney explicitly “black and white line art only” or “no color, no shading” — without this instruction, it often generates grayscale images with tonal variation that don’t translate well to coloring pages.
What I generated:
– 12 titles total
– 50 pages per book (minimum viable for KDP pricing)
– Mix of themed books (animals, space, ocean) and niche books (axolotl, capybara)
Time investment: About 4–5 hours per book to get 50 usable pages, including rejections and regenerations.
Step 3: Compile and Format (Week 2)
Amazon KDP requires PDFs in specific formats:
– Cover: 300 DPI, CMYK, specific trim size + bleed dimensions
– Interior: 300 DPI, black and white, PDF format
For the interior, I used Canva’s free version to:
1. Create a simple cover page template
2. Import each Midjourney image as a individual page
3. Add a title page and optional “This book belongs to ___” page
4. Export as PDF, ready for KDP upload
Canva’s KDP-specific templates saved me significant formatting time — I didn’t have to calculate trim sizes manually.
Step 4: Write Titles, Descriptions, and Keywords (Week 2)
This is where ChatGPT earned its subscription cost. I used it to:
- Generate title variations: “Give me 10 title options for an axolotl coloring book for kids ages 4-8, in the style of best-selling Amazon coloring book titles”
- Write 5 descriptions: Short (under 200 characters) for Amazon’s search algorithm + longer (under 2,000 characters) for the product detail page
- Brainstorm 7 backend keywords: 7 keyword phrases of up to 50 characters each, separate from the title
Important: Amazon’s algorithm treats the title as the primary ranking signal. Include the age range, the theme, and the word “coloring book” in that order (or near it) for best results.
Step 5: Publish and Monitor (Week 3)
KDP’s review process takes 24–72 hours. Once live, I checked daily for:
– Search ranking for my target keywords
– Conversion rate (views → purchases)
– Any formatting issues reported by buyers
Within 72 hours of my first listing going live, I had my first sale — an axolotl coloring book that ranked #3 for “axolotl coloring book” within a week.
My First 30 Days: Real Sales Data
Here’s the actual breakdown from my KDP dashboard for October 2025:
| Metric | Value |
|---|---|
| Titles listed | 12 |
| Titles with at least 1 sale | 8 |
| Total units sold | 134 |
| Total royalty income | $847.43 |
| Average price per book | $8.99 |
| Average royalty per unit | ~$6.32 |
| Tool costs | ~$47 |
| Net profit | ~$800 |
Top 3 performing titles:
1. “Axolotl Coloring Book for Kids Ages 4-8: 50 Fun Pages” — 41 units, $284
2. “Capybara Relaxation Coloring Book for Adults” — 29 units, $201
3. “Ocean Animals Coloring Book for Toddlers Ages 2-4” — 23 units, $159
Seasonal note: October was a tail-end warm-up for Q4. I launched just before the holiday buying season began — December sales on the same titles tripled.
What Actually Worked
1. Specific, niche themes beat generic ones. The axolotl book outsold my generic “Dinosaur Coloring Book” 3:1 despite having similar production quality. Specificity signals authority to Amazon’s algorithm and matches buyer intent more precisely.
2. Fast initial reviews matter. I asked 3 friends to buy and review within the first week. Amazon’s algorithm favors books with recent sales velocity, and a 4.5+ star review converts browsers to buyers.
3. Tiered pricing strategy. I priced at $8.99 for the 50-page books and $11.99 for 100-page books. The $8.99 price point converted better — I later raised the 100-page books to $9.99 and saw no drop in conversion.
4. Interior quality > cover quality. Parents who left reviews most often mentioned the “nice thick lines” and “easy for small hands to color.” The actual coloring experience drove repeat purchases and recommendations.
5. Backmatter works. I added a “If you enjoyed this book, check out my other titles” page at the back of each book. Cross-links between books drove bundle purchases from repeat buyers.
Mistakes I Made (So You Don’t Have To)
1. Too many thin lines in early generations. My first 2 books had pages with intricate details that frustrated testers. I learned to regenerate anything with line weights under 2pt at standard print size.
2. Ignoring KDP Select enrollment properly. I enrolled all books in KDP Select (required for certain promotional tools), which means they can’t be sold on other POD platforms simultaneously for 90 days. Plan your distribution strategy before enrolling.
3. Not building an email list from day 1. I had no way to notify buyers of new releases. Adding a simple “Follow my Amazon author page” CTA in the backmatter would have captured buyers interested in more titles.
4. Waiting too long to launch the second batch. I spent 3 weeks perfecting my first 12 titles before creating the next batch. A faster iteration cycle (launch smaller batches, measure, adjust) would have compounding effects on earnings.
How to Scale This in 2026
Since October 2025, I’ve refined the process significantly. Here’s what a more mature operation looks like:
Month 1–2: Launch 10–15 niche titles. Focus on underserved animal themes, profession-themed books for kids, and adult relaxation niches. Target: $500–$1,000/month.
Month 3–4: Identify your top 3 performers. Create derivative titles in those niches (volume 2, holiday editions, expanded page counts). Target: $1,500–$2,500/month.
Month 5–6: Expand to related categories (activity books, puzzle books, educational workbooks). Many of the same AI workflows transfer. Target: $3,000–$5,000/month.
The key insight is compounding catalog growth. Each new title has a shelf life of 12–18 months before it starts getting outranked by newer listings. A steady release cadence keeps the catalog fresh and increases the odds that at least one title catches a seasonal spike.
Tools I’d add at scale:
– Leonardo.ai as a second image generation source (better for consistent character styles across a series)
– Book Bolt for automated KDP niche research and listing optimization ($25/month)
– Amazon PPC ads once you have 10+ titles ($5–20/day budget, positive ROI with proper targeting)
Your Next Step
If you’re curious about this side hustle, here’s the minimum viable starting point:
- Sign up for Amazon KDP (free) at kdp.amazon.com
- Start a free Midjourney trial and spend 1 hour generating 10 line art images
- Pick your best 5 and compile them into a 20-page PDF using Canva
- Create a cover in Canva using KDP’s free cover template
- Upload and publish — your first listing can be live within 24 hours
From there, monitor your search ranking for target keywords and iterate based on real sales data.
The barrier to entry is genuinely low. The competition is real, but most new sellers give up before understanding what makes a niche coloring book actually sell. The ones who last long enough to figure it out tend to do well.
