Generating clean, printable coloring pages used to require hiring expensive illustrators on Fiverr. Today, you can use budget friendly AI image generators to create beautiful pages in seconds. I am going to show you the exact process to start this side hustle from scratch. This is a real, step by step guide to creating your first book and getting it in front of buyers.
Why AI Coloring Books Are a Great Side Hustle
Selling coloring books is highly profitable because the demand is always there. Adults use them to relieve stress, and parents buy them to keep kids quiet. The market is huge. With AI tools, you can create a complete book in a single weekend. You do not need to spend weeks drawing every single line by hand.
Let us talk about the money. A typical coloring book on Amazon sells for around $6.99 to $8.99. Amazon pays you about $2.00 to $3.00 in royalties for every sale. If you sell just five books a day, you can make around $300 to $450 a month. Once the book is live, that money keeps coming in without extra work. It's a genuine way to build passive income.
Of course, this isn't a get rich quick scheme. You won't make ten thousand dollars next week. It takes time to learn the tools, format your book correctly, and find the right niches. But if you are willing to put in the effort, the rewards are very real.
Finding a Profitable Coloring Book Niche
The biggest mistake beginners make is trying to sell a generic book. If you search Amazon for "kids coloring book," you will see millions of results. Your book will get lost on page fifty. You need to find a specific sub category where people are actively looking to buy, but there is less competition. This is called finding a niche.
Instead of a general dog coloring book, you could make a "Corgi dogs wearing funny hats coloring book." Instead of a simple adult coloring book, you could create "gothic fantasy castles for fantasy fans." Here is how you can find these hidden niches on Amazon:
- Type a broad term into the Amazon search bar and look at the auto suggestions. These are things real people are searching for.
- Look for books with a Best Sellers Rank under 100,000. This proves people are actually buying them.
- Check the competition. If there are fewer than 1,000 search results for a specific phrase, you have a great chance to rank on the first page.
Spend a few hours doing this research before you generate a single image. A great niche makes up for poor marketing. If you choose the wrong niche, even the most beautiful drawings will not sell.
How to Generate High Quality AI Coloring Pages
Once you've got your niche, it's time to create the artwork. The best tool for this is Midjourney, but Leonardo AI is also a fantastic free alternative. To get clean coloring pages, you need to write the right prompts. AI models love to add shadows and gray gradients, which look terrible in a coloring book. You want pure black lines on a clean white background.
Here is a prompt formula that works incredibly well in Midjourney:
"Coloring page for adults, [insert your subject here], clean line art, bold black lines, pure white background, low detail, no shading, no gradients, 8k --ar 4:5 --v 6.0"
If you want to make a book about cozy cabins, your prompt would look like this: "Coloring page for adults, cozy cabin in the woods with a fireplace, clean line art, bold black lines, pure white background, no shading --ar 4:5". The "--ar 4:5" part sets the aspect ratio so it fits perfectly on a standard book page.
Do not accept the first image the AI gives you. Keep variations going until the lines are perfectly sharp. If there are small gray areas, you can use free photo editors like Photopea to turn up the contrast. This makes the whites whiter and the blacks blacker.
Creating digital assets with AI requires some practice, but it is highly rewarding. This is very similar to how people are building a faceless YouTube channel with AI to build passive income streams. Both methods require you to master prompt writing and content curation to succeed.
Putting Your Coloring Book Together on Canva
Now you need to turn your individual images into a complete book. You can do this easily using Canva, which is free. Create a new design with custom dimensions. The standard size for coloring books on Amazon is 8.5 by 11 inches. Make sure to set your design to this exact size.
When you place your images, always leave a blank page behind each drawing. This is important because coloring markers often bleed through the paper. If you put drawings on both sides of a page, the customer will ruin the next drawing when they color. A standard forty page coloring book will actually have eighty total pages in your PDF file.
Make sure your images do not go too close to the edges of the page. Amazon needs a small margin, called the gutter, so the book can be bound without cutting off your drawings. Keep all your main art at least 0.5 inches away from the borders. Once everything looks perfect, download your design as a "PDF Print" file. This format ensures high resolution when Amazon prints the physical book.
Designing a Cover That Grabs Attention
People absolutely judge books by their covers. Your cover is the most important element for getting clicks on Amazon. While the inside pages are black and white, your cover must be bright, colorful, and eye catching. It should clearly show what kind of drawings are inside the book.
You can use Canva to design your cover as well. You will need to download a cover template from the Amazon KDP website first. This template shows you exactly where the spine and barcode will go based on your page count. Upload this template to Canva and design over it.
Use a colored version of one of your best inner pages on the front cover. Show a few smaller previews of the inside pages on the back cover. This builds trust with buyers because they want to see what they are paying for before they click add to cart.
Uploading and Pricing Your Book on Amazon KDP
Creating your KDP account is free and takes five minutes. When you upload your book, you will need to fill out the title, subtitle, and description. Use natural keywords in your subtitle that people might search for. If your book is about cars, your subtitle could be "Fun coloring pages with classic cars, sports cars, and vintage trucks for adults and teens."
Do not stuff keywords in a way that looks like spam. Keep it natural and helpful. In the keyword slots, use phrases you found during your niche research. For pricing, look at what your competitors are doing. Pricing your book at $7.99 is usually the sweet spot for a standard forty page book.
Once you hit submit, Amazon will review your book. This process usually takes between twenty four and seventy two hours. Once approved, your book will be live on Amazon, ready for customers around the world to buy.
Your immediate next step today is to sign up for a free Canva account and search Amazon for three potential coloring book niches. Pick one niche and generate your first three images using Leonardo AI or Midjourney. The sooner you start practicing, the sooner you will have your first book making sales on Amazon.
