How to Publish a Coloring Book on Amazon KDP in 2026: Step-by-Step

June 15, 2026 · 12 min read · By Prasad Chandrasekaran, KOKOMA Press

Publishing a coloring book on Amazon KDP in 2026 is more competitive than it was three years ago, but it's also more lucrative for creators who know what they're doing. The Mosaic Art bestseller list — where most of the well-monetized coloring book niches live — is dominated by indie publishers running tight, repeatable workflows. The best of them are pulling $20K–$80K per month per active series.

I publish under KOKOMA Press and run Color By Number Pro, the tool I built to ship my own books faster. This is the exact workflow I use, plus the parts most beginner guides skip.

What's in this guide
  1. Picking a profitable niche
  2. Generating or sourcing your images
  3. Building the book interior
  4. Designing the cover
  5. Uploading to KDP
  6. Pricing and royalties
  7. Launch tactics
  8. Tools indie publishers actually use

Step 1: Pick a profitable niche

Most beginner mistakes happen here. A coloring book is a product — and product-market fit on Amazon is decided by what the BSR (Best Sellers Rank) tells you. Browse the Mosaic Art bestseller list for 20 minutes and you'll see the pattern: it's not "adult coloring book" anymore. It's narrow, repeatable themes:

Rule of thumb: if you can't describe the niche in 4 words ("100 Mystery Mosaic Birds"), it's too broad. Top-selling KDP coloring books read like product SKUs, not artistic statements.

How to validate before you publish: Use Publisher Rocket or DataSpark to check Amazon search volume + competition for your niche keyword. A good signal: monthly Amazon searches in the 1,000–10,000 range with fewer than 200 competing books. If both numbers are too high, you'll be invisible. If both are too low, no one is searching.

Step 2: Generate or source your images

Once you have a niche, you need ~50–410 distinct images. There are three paths:

A) AI-generated illustrations

Midjourney, DALL·E, and Stable Diffusion are the indie standard. You'll burn 5–15 hours generating + curating 100 images. Watch out for KDP's content policy: AI-generated images must be disclosed during upload, and Amazon scans for AI artifacts that violate quality standards.

B) Licensed stock illustrations

Sites like Vecteezy, Freepik, and Creative Fabrica sell pre-cleaned vector illustrations specifically for coloring books. Faster than AI, but you're using assets other publishers also use — your book won't be unique without significant editing.

C) Personal photos

For pet portrait books, memorial books, family albums, or themed photo-based mosaics. This is where color-by-number-from-photo tools become essential.

Step 3: Build the book interior

This is where most creators waste 30+ hours. Each color-by-number page requires: image segmentation, color clustering, number assignment, edge cleanup, page numbering, and a matching color reference key. Doing this manually in Photoshop or Illustrator takes 20–40 minutes per page. For a 100-page book, that's 35–65 hours.

The serious indie KDP publishers I know all use a generator. The two paths:

1. Online generators (free tier)

Decent for one-off pages, but most cap you at 1 image, watermark the output, or charge per export. Useful for testing the workflow once.

2. Desktop generators (paid, one-time)

Tools like Color By Number Pro Premium let you batch-process 100–410 images in one session, pick from 5 cell shapes (square / hex / circle / diamond / triangle) per individual page, customize the color palette, and export a full KDP-compliant PDF interior with table of contents, copyright page, answer keys, and page numbers — all in one click.

The shape choice matters more than people think. Hexagon cells produce a denser, more "mystery mosaic" look. Squares are classic. Diamonds and triangles create tessellation patterns. Mixing shapes across pages in a book gives the customer variety, which drives reviews.

KDP technical requirements you can't skip: 300 DPI minimum, exact trim size (8.5×11 or 8.5×8.5 are most common for coloring books), 0.125" bleed on all sides, embedded fonts, single-page PDF (not spreads), CMYK or RGB depending on print path. A good generator handles all of this for you. A bad workflow means rejection at upload.

Step 4: Design the cover

Your cover earns the click — interior earns the review. Spending 40 hours on interior and 30 minutes on cover is the #1 reason indie KDP books fail to sell despite being well-made.

Look at the bestseller list: the covers all follow the same conventions:

Tools: Canva (free, fast, has KDP templates), Affinity Publisher ($70 one-time), or Photoshop. Don't outsource your first 3 covers — you need to learn what works in your niche before paying a designer $200/cover.

Step 5: Upload to KDP

The actual KDP upload is the easiest step. From kdp.amazon.com:

  1. Create new paperback title (coloring books are paperback, never Kindle eBook)
  2. Title + subtitle: include your primary keyword in the subtitle (e.g., "100 Mystery Mosaic Animals: Color By Number Coloring Book for Adults")
  3. Series name if you're building multiple books — Amazon groups series titles together on author pages
  4. 7 keywords in the keyword fields — use Publisher Rocket to pick high-volume / low-competition phrases
  5. 2 categories — request 8 more via KDP Help to maximize bestseller-badge eligibility
  6. Print options: Black & white interior on white paper is cheapest and standard for coloring books
  7. Upload interior PDF — the previewer will flag any issues; fix immediately, don't proceed with warnings
  8. Upload cover — generated from KDP's free cover creator OR your own PDF
  9. Pricing — see step 6
  10. Publish — title goes live in 24–72 hours

Step 6: Pricing and royalties

KDP coloring books typically retail at $6.99 to $12.99. Pricing depends on page count:

Your royalty is 60% of list price minus print cost. For a 100-page black & white coloring book priced at $9.99:

The competitive bestseller list shows top books selling 30–150 copies per day. At $3.94/copy, that's $3,500–$17,500/month per active title. The math works once you stack 3–10 titles in a series.

Step 7: Launch tactics

Amazon's algorithm favors books that sell quickly in their first 30 days. To trigger the algorithm:

Step 8: The tools indie KDP publishers actually use

After 3+ years of publishing under KOKOMA Press, here's my actual stack:

Total monthly recurring: ~$60. One-time investment to get started: ~$300. That's the entry cost to run a serious KDP coloring book business — which can earn $3K–$30K/month per active series after 6–12 months.

FAQ

Do I need a publisher account to upload to KDP?

No. KDP is open to any individual with an Amazon account, a bank account, and a tax ID. You can publish under your real name or set up a publisher imprint (like KOKOMA Press) for branding.

How long does it take to publish my first coloring book?

With a good workflow, 8–20 hours from idea to live on Amazon. Most of that time is niche research + cover design, not interior creation — assuming you use a proper coloring book generator.

What's the minimum number of pages?

KDP requires at least 24 pages for paperback. Practically, 50–100 pages is the sweet spot for coloring books — enough to feel substantial without pushing the print cost too high.

Can I publish if I'm outside the US?

Yes — KDP pays international royalties. You'll need to fill out a US tax form (W-8BEN) which KDP guides you through. Royalties pay in your local currency to most bank accounts.

How many books do I need to make a living?

The math: if your average active book earns $400–$1,000/month (typical for a well-niched title that's been on Amazon 3+ months), you need 5–10 active titles to replace a job income. Most full-time KDP publishers I know have 15–50 active titles in their catalog.
