How to Create a Color-By-Number Book for Amazon KDP

Color-by-number and mystery mosaic coloring books are one of the fastest-growing niches on Amazon KDP. Top sellers earn thousands per month from books that cost nothing to print (Amazon handles everything). In this guide, I'll walk you through the exact process of creating and publishing your first color-by-number book.

What You'll Need

• High-quality images — photos of animals, landmarks, flowers, food, or any subject
• A color-by-number generator — software that converts images into numbered grids
• An Amazon KDP account — free to create at kdp.amazon.com
• A book cover — you can create one with Canva or hire a designer on Fiverr

Step-by-Step Process

1 Choose Your Niche

The most popular color-by-number niches on Amazon include:

• Animals — wildlife, pets, birds, ocean creatures
• Nature — flowers, landscapes, trees, gardens
• Food — fruits, desserts, drinks, kitchen scenes
• Landmarks — famous buildings, cities, travel destinations
• Holidays — Christmas, Easter, Halloween themed books
• K-Pop / Pop Culture — trending topics with built-in audiences

Look at the Amazon Best Sellers in the "Color-by-Number" category to see what's selling right now. Find a niche with demand but not too much competition.

2 Gather Your Images

You need 30-100 high-quality images for a typical book. Sources include:

• MidJourney or DALL-E — AI-generated images work great for coloring books
• Unsplash / Pexels — free stock photos (check license for commercial use)
• Your own photos — original content is always best

Choose images with clear subjects, good contrast, and distinct colors. Simple compositions work better than complex scenes — the numbered grid needs to be readable.

3 Generate Your Color-By-Number Pages

This is where the magic happens. Upload your images to a color-by-number generator and configure your settings:

• Grid size — Detailed (more cells, harder), Medium, or Simple (fewer cells, easier)
• Colors — 8-48 colors depending on complexity
• Cell shape — Square (classic), Circle, Hexagon, Diamond, or Triangle
• Book size — 8.5x11 inches is the most popular KDP size

For each image, the tool generates:

1. Color page — the mosaic artwork (answer key for colorists)
2. Number page — the actual coloring page with numbered cells
3. Palette page — color reference showing which number = which color

4 Assemble Your Book Interior

A typical color-by-number book includes:

1. Title page
2. Copyright page
3. Instructions / How to use this book
4. Table of contents (optional)
5. The color-by-number pages (number page + palette page for each design)
6. Answer key section (color pages showing the finished artwork)

Export everything as a single PDF at 300 DPI. This is the file you'll upload to KDP.

5 Create Your Book Cover

Your cover is the #1 factor in whether someone clicks on your book. Tips:

• Show a sample completed design — let buyers see what they'll create
• Use bold, readable text — the title should be clear even as a thumbnail
• Include the number of designs — "50 Designs" or "101 Unique Mosaics"
• Add a small mosaic preview showing the numbered grid style

You can use Canva (free) or hire a designer on Fiverr ($15-50) for a professional cover. KDP provides a cover template with the exact dimensions you need.

6 Publish on Amazon KDP

1. Go to kdp.amazon.com and sign in
2. Click "Create" → "Paperback"
3. Fill in: Title, Author name, Description, Keywords (7 keywords)
4. Upload your interior PDF and cover
5. Set your price (typically $8.99-$12.99 for coloring books)
6. Click "Publish"

Your book will be live on Amazon within 24-72 hours. KDP handles all printing, shipping, and customer service. You earn royalties on every sale.

How Much Can You Earn?

Earnings vary widely, but here's a realistic breakdown:

• Beginners (1-5 books): $100-500/month
• Intermediate (10-20 books): $500-2,000/month
• Serious publishers (50+ books): $2,000-8,000/month
• Top sellers (100+ books in good niches): $10,000+/month

The key is volume and niche selection. One book might earn $50/month, but 20 books earning $50 each = $1,000/month passive income.

Tips for Success

• Publish consistently — aim for 2-4 books per month
• Research keywords — use tools like Publisher Rocket or the Amazon search bar
• Study competitors — look at bestselling books in your niche for inspiration
• Get reviews — send free copies to friends, family, or coloring communities
• Experiment with cell shapes — hexagon and circle mosaics stand out from square-only competitors
• Create series — "Vol. 1", "Vol. 2" encourages repeat purchases
