The Coloring Book Craze Isn’t Going Anywhere—Here’s Why You Should Jump In Now!

Let’s be real—coloring books are the perfect escape. Whether it’s adults looking for a relaxing way to unwind, kids diving into creativity, or anyone trying to ditch screen time for something more hands-on, coloring books are here to stay.

And guess what? Selling them is one of the easiest ways to make money online—if you do it right.

In 2025, self-publishing coloring books is one of the smartest ways to generate passive income. Platforms like Amazon KDP and Etsy make it ridiculously simple to start selling, and with the right niche, you can tap into a market that’s always hungry for something fresh and exciting.

But let’s be honest—standing out in a sea of generic mandalas and floral patterns? Not so easy. The customer scrolling through a busy marketplace, faced with hundreds of coloring book options, must see your product and think: "This coloring book GOT IT." 

That’s why I’ve rounded up five unique and high-potential coloring book ideas that can set you apart and maximize your sales.

These aren’t just any ideas—they’re proven to have massive appeal, and many sellers are already cashing in on these pre-made designs. The sooner you jump in, the better your chances of effortless sales before the market catches on. So, let’s dive in! 

This coloring book concept is fun, visually appealing, and perfect for all ages. The 800+ page pack available comes in multiple formats (JPG, PNG, PDF) and even includes Canva and full PLR rights, giving you endless possibilities to edit and brand the designs as your own.

Why does this idea work so well? Because it’s a fresh take on something familiar. People love nature-themed art, but adding a fantasy twist like fruit-shaped houses makes it even more irresistible.

It appeals to colorists who enjoy intricate details, whimsical designs, and creative storytelling. Plus, it makes for a fantastic children’s coloring book that parents can’t resist.

🔹 Pro tip: Since fruit houses pair beautifully with vegetable-themed designs, consider bundling them together for an even bigger product line!

This concept is nothing short of mesmerizing, making it a dream coloring book for fantasy lovers. With 650+ pre-made pages, you can start selling immediately without having to spend weeks creating designs from scratch.

Fantasy and micro-world concepts are trending, and coloring enthusiasts (kids and adults alike) can’t get enough of them. Whether it’s a child imagining their own tiny kingdom or an adult escaping into a beautifully detailed world, this coloring book idea has huge potential to be a bestseller.

🔹 Pro tip: You can create a whole series of Worldbox-themed books—seasonal editions, fairy tale editions, or even sci-fi editions!

Aside from being fun, this coloring book concept also has an educational angle. Parents and teachers are always looking for creative ways to introduce kids to vegetables and healthy eating habits, making this book a must-have in their collection.

With a 700+ page pack, you’ll have everything you need to launch your own line of vegetable-themed coloring books. And like I mentioned earlier, combining Fruit Houses + Vegetable Houses can create a larger food-themed coloring collection that has even higher sales potential.
