Color-by-number is an evergreen niche on Amazon — and it's only getting bigger.

While most KDP niches spike and fade with trends, color-by-number has done the opposite. Adult mosaic and mystery-mosaic books have sat in Amazon's Top 100 Coloring Books for years — not weeks. The demand isn't seasonal: people color in January, July, on planes, in hospital waiting rooms, after work, before bed. Search volume for "color by number adults" has climbed every single year since 2018, and stress-relief and screen-fatigue tailwinds keep pulling new buyers in.

That's why this is the rare KDP niche where a good catalog compounds. Books from 2021 still earn royalties today. Series buyers come back for Volume 2, Volume 3, themed editions. Once you have 10–20 quality titles in a coherent imprint, the long tail does the selling for you. Premium exists because building that kind of catalog by hand — in Photoshop or Canva — is what kills most publishers before they get to book three.

Proven Demand

The top 10 are already making real money on Amazon.

Not a single big-five publisher made this list. Every book below is from an independent imprint — Pixelcolorist Books, Malie Kokoro, Pipo Pixel, Sunlife Drawing — mostly solo creators with off-the-shelf tools. The #1 title earns an estimated ~$28K per month. The #10 title still pulls in roughly ~$9K per month. Together, the top 10 generate over $130K per month — from this one bestseller list alone.

Two patterns repeat in every winner. First, the mystery-mosaic format — pixel cells that hide a picture until you color it. Second, series-building: Malie Kokoro appears twice on this list with 80's Vibes and 90's Vibes, the same recipe applied to a new theme. KOKOMA Press sits at #8 — built with the same Premium system you're looking at right now. The barrier isn't talent or budget. It's having a tool that can produce a 100-book catalog without burning you out by book three.

So how do you actually beat those top sellers?

Look at the bestseller list above. Those books sell — and they sell really well. They're living proof of serious demand on Amazon, and that demand has only grown over the years.

But notice something. They all look almost the same. Same square cells. Same default palettes. Same 50-to-100-page layout. Same repetitive feel.

When every book looks and feels the same, buyers struggle to tell them apart — and when everything looks the same, nothing stands out. Color-by-number enthusiasts aren't leaving the niche. They're getting tired of solving the same kind of book over and over. Many are actively searching for something more visually striking, more challenging, more premium… but they rarely find it.

That gap is your opportunity. The marketplace is overloaded with basic square-grid mosaics, but there are very few books featuring per-page cell shape variety, hand-curated color palettes, answer keys, and themed series collections — not because publishers don't want to make them, but because they're too time-consuming, too technical, and too hard to produce with standard tools. That's exactly the gap Premium fills.

Creating and selling premium color-by-number books on KDP is SIMPLE…

Step #1 Generate your color-by-number pages

Pick an image. Pick your cell shape — square, hexagon, diamond, circle, or triangle. Pick your custom 48-color palette. Premium does the rest: it converts the image, numbers every cell, applies the palette, and exports a clean, print-ready page. What used to take hours in Photoshop takes minutes here.

Step #2 Build the full book in one PDF

Repeat for up to 410 images per book. Premium auto-generates the answer keys, the table of contents, and consistent page numbers as you go. Drag-reorder pages, choose your book size, set your margins. Hit Export and walk away with a single print-ready KDP interior PDF.

Step #3 Upload to KDP. Collect royalties monthly.

Upload your PDF and cover to Amazon KDP. Set your price. Hit Publish. Amazon prints on demand, ships worldwide, and pays you royalties every single month — for as long as the book sells.

And yet, most publishers never finish their first book — here's why.

#1. You'd need to be an artist, a typesetter, and a math nerd — at the same time.

Building a real color-by-number page isn't just "draw a picture." It needs vector geometry to construct per-image cell shapes (square, hexagon, diamond, circle, triangle). Typography chops to lay out clean numbered grids. A math head to keep your palette, numbering, and answer-key references in sync across hundreds of pages. Most indie publishers are good at one of these. Almost no one is good at all three.

Cartoon illustration of the publisher overwhelmed by Photoshop interface

#2. One book takes a month of nights. Welcome to your weekends.

A 100-page color-by-number book isn't 100 colored pictures. It's 100 numbered pages, 100 answer-key references, a master palette legend, a TOC, and print-bleed margins on every spread. At even 30 minutes per page, that's 50+ hours of manual labor per book — done after your day job, around the kids, late at night, fueled by coffee. By book three, you're done. You can already see why most publishers tap out before finishing their second title.

Cartoon illustration of the publisher buried in coloring book pages late at night

#3. Reorder one page and the whole stack starts screaming.

Want to swap pages 32 and 48 because the difficulty curve felt wrong? Cool. Now renumber every page. Rebuild every answer-key reference. Update the TOC. Re-check your bleeds. Re-check your spreads. One missed alignment and the whole book is wrong. The publishing world has a phrase for this loop — the maintenance death spiral — and it's why most KDP coloring publishers quit by their third title.

Cartoon illustration of the publisher tangled in numbered pages and sticky notes

#4. A series of ten? That's a job for an army, not a person.

Even if you ship one book by hand, doing 10, 20, or 50 of them — same brand voice, same cell-shape rhythm, same palette family, matching cover style — is practically impossible without a system. The bestseller authors you saw earlier didn't will those catalogs into existence by working harder. They built systems. That's the moat. And it's the moat most indie publishers never cross.

Cartoon illustration of the publisher overwhelmed by stacks of incomplete books

#5. Hiring help looks smart — until you do the math.

Freelance illustrators charge $50 to $200 per finished page. A 100-page book? $5,000–$20,000 spent before you sell a single copy. A 10-book series? The cost of a small car. And you still have to QA every page yourself — because you're the one whose name is on the listing when something's wrong. Outsourcing isn't an escape from this problem. It's a more expensive version of the same problem.

Cartoon illustration of the publisher shocked by freelance invoices and costs

#6. KDP's print-spec gauntlet will eat your evenings whole.

Amazon's interior PDF requirements are unforgiving: exact bleed margins, exact trim sizes, embedded fonts, 300 DPI images, CMYK color profile, file size under 650 MB. Miss any single one and KDP rejects your upload with a cryptic error. Now you're debugging a 60-megabyte PDF at midnight, three hours before your launch deadline, with no idea which page is the culprit. This is the part the "easy KDP income" videos never show you.

A Curious Fact

Notice something missing from that bestseller list? The big publishers.

Look back at the top 10. Pixelcolorist Books. Malie Kokoro. Sunlife Drawing. KOKOMA Press. All independent imprints — solo creators or tiny duos.

No Penguin. No HarperCollins. No Disney. No Crayola. The big publishers want this niche. They watch the charts every week. They have the budgets to drown out indies. And yet — they keep failing to crack it.

Cartoon of confused publishing house executives looking at bestseller charts

Why? Because the win condition here isn't one beautiful book. It's a coherent catalog of 20+ books — same visual identity, consistent quality, fast enough to chase emerging trends. Big publishers solve that with armies. Indies solve it with systems. And until now, the right system didn't exist at indie price points.

What the big publishers have that you don't:

In-house art directors
Six-figure production budgets
Senior layout designers
Full-time QA and proofing staff
Premium typography licenses
Marketing teams pushing every release

Cartoon of a busy publishing house production team

They have everything you don't — and they still can't catch the indies. That tells you everything you need to know about this niche.

Your options are limited

Until today, you only had three ways to build a serious color-by-number catalog. All three were traps.

Option #1

Build every book by hand, yourself

You can learn Photoshop, master vector grids, hand-number every cell, manually rebuild every answer key, hand-tune every print bleed. You'll ship book one in a month. You'll burn out by book two. You'll quit by book three. This is how 90% of indie publishers fail — they pick the slowest possible path and run out of energy before the catalog compounds.

Option #2

Pay freelance illustrators per page

You can hire designers at $50–$200 per finished page. A 100-page book = $5K–$20K out of pocket. A 10-book series = the cost of a small car, spent before you've sold a single copy. And you still QA every page yourself — because your name is on the listing when something's wrong. The math kills the business before the catalog ships.

Option #3

Engineer your own production system

You can build the workflow yourself — vector pipeline, palette manager, auto-numbering script, answer-key generator, PDF compiler. It works. It also takes 6 to 12 months of focused programming and a quarter-million in opportunity cost. Spoiler: I already did this. That's exactly why Premium exists.

Meet the Founder

I built this because I was the customer. Now it's yours.

Prasad Chandrasekaran, founder of Color By Number Pro and publisher at KOKOMA Press

Hi — I'm Prasad. I run KOKOMA Press, the mystery-mosaic coloring book imprint sitting at #8 on the bestseller list you saw earlier on this page. Before this tool existed, I was building those books the slow, painful way the "Reality" section above describes.

Every problem in that section is one I lived through. The Photoshop hell. The 50-hour books. The renumbering death spiral. The freelancer math that didn't add up. The midnight KDP-spec errors. By book three, I had two choices: quit, or build the system I wished existed. I chose to build it.

For two years, this was my private tool — the only reason KOKOMA Press has a catalog at all. I'm releasing it now because the indie color-by-number niche is big enough for hundreds of us, and the tool would gather dust as a private project. If it's good enough to run my business on, it's good enough to put in yours.

Introducing

Color By Number Pro — Premium Edition

Color By Number Pro Premium is a browser-based publishing app that turns any image — a photograph, a vector design, an AI-generated render — into a complete color-by-number book interior, ready to upload to Amazon KDP.

It generates the two formats dominating the 2026 Amazon coloring charts: Mystery Mosaics (numbered cells revealing a hidden image) and Black-Background Mosaics (the premium-positioned variant the top 10 are riding right now).

Nothing to download. Nothing to install. Nothing to maintain. It runs in your browser, on any modern OS, from any computer.

Cartoon of a creator using Color By Number Pro from her home office laptop

Open it from any laptop, any cafe, any hotel room. Drop in your photo. Pick your cell shape, your palette, your color count. Hit Generate. Walk away. Come back ten minutes later to a print-ready KDP interior PDF.

The output doesn't look "indie-made." It looks like a book from a mid-size publisher with a six-figure production budget. The Amazon buyer who picks up your book can't tell the difference between you and Pixelcolorist Books — except that you shipped yours faster.

It's the closest thing I know to having an art director, a layout designer, and a print-prep technician on call 24/7 — without the $400K-a-year salary line.

How It Works

Four simple steps to ship a bestseller-quality color-by-number book.

From a blank screen to a print-ready KDP interior PDF — under an hour on your first book, under 15 minutes on every book after.

Step #1 Drop in your images

Drag and drop up to 410 source images in a single batch. Premium accepts PNG, JPG, JPEG, and WebP — your AI renders, your photos, your vector artwork, all in one queue. Watch the thumbnails populate in real time, then move on while the engine prepares your interior.

Color By Number Pro — Upload images interface

Step #2 Tune your style and structure

Choose your book size (six KDP-ready presets plus custom). Set your grid complexity. Pick one of five cell shapes — square, hexagon, diamond, circle, or triangle — per image if you want. This is where your book gets its visual identity. Save it once and Premium remembers it for the next book in the series.

Color By Number Pro — Book size, grid, and cell shape settings

Step #3 Lock in your palette

Choose anywhere from 8 to 48 colors. Use a preset palette, build your own with the color picker, hide white for transparent backgrounds, or switch to letters for any value above 9. The palette page also becomes the legend in the printed book — no manual page-building required.

Color By Number Pro — Color palette picker

Step #4 Export a print-ready KDP interior

Hit Export. Premium hands you the full book interior as a ZIP of per-page files or a single KDP-ready PDF — complete with table of contents, copyright page, answer keys, and page numbers. Vector output, fonts embedded, exact KDP bleeds. Upload to Amazon. Hit Publish. Start collecting royalties.

Color By Number Pro — Export your book screen

From opening the app to KDP "Live" status: under 60 minutes on your first book. Under 15 on every book after that.

Inside Premium

Here are the features the bestsellers had to build by hand.

Every one of these is a wall most KDP coloring publishers hit by book three. Premium ships them already-solved on day one.

KDP-ready output

One-click KDP PDF — print-ready, every time.

Hit Export. Premium hands you a complete book interior PDF with palette page, number page, answer key, table of contents, title page, and copyright page — every piece Amazon's print pipeline expects.

No format errors. No upload rejections. No 2 AM debugging chasing cryptic KDP error codes. One click. Print-ready. Every time.

Surgical control

Edit cells — fix odd areas without regenerating.

Spot a cell that's the wrong color? Click it. Repaint it. Done. No regenerating the whole image, no losing your other edits, no starting over.

This is the difference between a tool that "almost works" and one that respects your creative time. Photoshop would force you all the way back to step one. Premium fixes it in one click.

A finished color-by-number page mid-edit — click any cell to repaint it instantly

KDP-compliant

KDP margin guides — visible while you build.

See exact print margins, bleeds, and safe zones drawn live on the preview canvas. Move your image around the page and watch the safe boundaries adjust in real time.

Every PDF Premium exports is KDP-compliant out of the box — because you can see what's safe and what's not while you're still editing, not after Amazon rejects the upload.

No wasted uploads

Preview before export — see every page in your browser.

Preview your complete book PDF right inside the browser before you save a single byte. Flip through every page. Catch the off-page number that needs a tweak. Edit, re-preview, then export.

No wasted KDP uploads. No Amazon rejection emails. What you see is exactly what your buyer will color.

Preview your book pages live in the browser before exporting — a finished octopus mosaic page from a real KDP book

Brand control

48 custom colors — full RGB picker, save and reuse.

Use one of the presets or build your own with the full RGB picker. Hide white for transparent backgrounds. Switch to letters for any value above 9 (so a 24-color page reads cleanly without three-digit numbers). Save palettes for the next book in the series.

Match your brand identity exactly — the way the indies winning today's bestseller list already do.

48-color custom palette picker inside Color By Number Pro

No more manual labor

Auto answer key — zero mismatches, ever.

Premium auto-generates the color-reference answer key pages that match your palette and numbering. Reorder pages? Renumber on save. Add or remove a chapter? Everything cascades automatically.

This single feature is why most KDP coloring publishers quit by book three — and it's the one Premium absolutely refuses to make you do by hand.

Auto-generated color reference and answer key page

Cell Shapes

Five cell shapes — per image, in the same book.

Most generators force one global cell shape on every page. Premium lets you pick a different one for every page. Build a visual identity competitors can't copy with a single click.

Square

Classic grid style. Clean, familiar, easy to color.

Circle

Soft, rounded mosaic. A distinct artistic look.

Diamond

Rotated squares. Elegant, geometric, modern.

Triangle

Bold tessellation. Striking, angular, dynamic.

Hexagon

Honeycomb pattern. Rich, detailed, premium feel.

Mix all five inside one 100-page book. No other generator at indie price points does this.

Still here reading?

You've scrolled past fifteen sections. Past the bestseller chart. Past the gap analysis. Past the Photoshop hell. Past the three options that are all traps. Past every feature, every screenshot, every problem. That means something.

It means the niche makes sense to you. The system makes sense. The offer is starting to feel less like a stretch and more like the obvious move. And it means you're seriously considering the kind of decision most KDP publishers never make — investing in the right tool before they grind through their first book by hand.

Amanda was you, eleven months ago. The forty-seven reactions on her review weren't strangers — they were KDP publishers who scrolled exactly this far and recognized what they were looking at.

The Real Math

Premium isn't the cheap option. It's the only sane one.

Here's what shipping bestseller-quality color-by-number books actually costs — depending on which approach you pick.

Approach	What you actually spend
Photoshop + InDesign, by handAdobe Creative Cloud subscription — plus 200+ hours per book you build manually	~$720/year + your evenings
Hire freelance illustrators per page$50 to $200 per finished page × ~100 pages per book — before you sell a single copy	$5,000 – $20,000 per book
Engineer your own production systemVector pipeline, palette manager, auto-numbering, PDF compiler — 6 to 12 months of focused programming	~$50K+ in opportunity cost
Hire a small in-house production teamDesigner + layout artist + proofreader on payroll — the path big publishers take, and still can't crack the bestseller list	$200K+ per year
Color By Number Pro PremiumEverything above — productized, ready in your browser, refundable for 7 days	$97 — one time

Four ways to spend more money, more time, or both. One way to spend less of either. Premium isn't the expensive choice — it's the only choice that isn't.

FAQ

Questions you might be holding onto.

What exactly do I get with Premium? ▼

Every feature unlocked: 410 images per session, all 5 cell shapes with per-image selection, 48 customizable colors with RGB editing, 6 KDP book sizes plus custom margins, drag-reorder pages, auto answer keys, auto table of contents, live cell editing, palette editing, the 10-video step-by-step course, full commercial license, lifetime updates, priority email support, founder-direct custom feature requests, 25% off any future tool I ship, and a 7-day money-back guarantee. Total stack value: $973. Founders Launch (first 500 customers): $97.

What's your refund policy? ▼

7 days, no questions asked. Email support@colorbynumber.pro within 7 days of purchase and I'll refund every cent through WarriorPlus. No forms, no proof required, no follow-up emails. Refunds process within 48 hours.

Will the price stay this low? ▼

No. The Founders Launch price ($97) is for the first 500 customers only. After that, the public price returns to the regular Premium tier. Founders Launch buyers lock in lifetime access at $97 with no recurring fees, ever.

Can I really put different cell shapes on different pages? ▼

Yes — this is a Premium-only feature. After uploading your images, click any thumbnail and assign that page its own cell shape (Square, Circle, Hexagon, Diamond, or Triangle). Mix freely within a single book — great for themed sections inside a larger volume, or for visually distinguishing books in a series.

How do answer keys work? ▼

Premium auto-generates a fully colored answer-key page for every numbered page in your book. Include them at the back (KDP-style) or omit them. Many premium-priced coloring books on Amazon use answer keys as a differentiator — Premium gives you the same advantage without any manual page-building.

I'm a beginner — is this overkill for me? ▼

Not really. The basic workflow (upload → customize → export) is the same whether you're building your first book or your fiftieth. The advanced features (per-image shapes, custom palettes, answer keys, TOC) sit quietly until you reach for them. Most buyers go straight in because they don't want to hit a ceiling halfway through book three and have to migrate to a different tool.

Can I sell the books I create? ▼

Yes. Premium includes a full commercial license. Sell on Amazon KDP, Etsy, Gumroad, Creative Fabrica, your own website — anywhere. Keep 100% of the revenue. No royalties, no usage limits, no series caps.

Where does the app run? Do my images go to a server? ▼

Premium runs in your browser on any modern OS. Your images never leave your computer — all processing happens locally inside the app. No cloud upload, no server-side rendering, no privacy concerns. Works on Mac, Windows, Linux, and Chromebook.

Is this a subscription? ▼

No subscription. Ever. One-time payment of $97. Lifetime access. All future updates included free. No credit card on file, no surprise charges, no annual renewal.

What's the "founder-direct feature request" bonus? ▼

Email me a feature you wish Premium had. If it fits the broader roadmap, I build it and ship it — usually within a week. This is exactly how Amanda got the export/import palette feature: she asked, I shipped a new version within hours. Founders get the same direct line.

How do I get support if I'm stuck? ▼

Email support@colorbynumber.pro. Premium customers jump the queue — I respond to Premium emails first, usually within a few hours. No ticket queue, no canned responses, no chatbot. A real human, every time.
