Color by Number for Adults: Why This Trendy Format Is More Than Just Following Rules

If you think color by number is just for kids, you are missing one of the fastest-growing trends in adult <a href="https://coloredcalm.com/fix-<a href="https://coloredcalm.com/summer-Coloring-setup-how-to-create-the-perfect-outdoor-and-travel-coloring-station/”>Coloring-mistakes-without-starting-over-2/”>Coloring. Walk into any bookstore or browse Amazon’s coloring book bestsellers, and you will see them dominating the charts. Adult color by number books combine the stress relief of coloring with the structured guidance of a paint-by-numbers format, and the result is surprisingly addictive.
But is it actually good for you, or is it just a gimmick? And how do you choose the right book and supplies when there are hundreds of options? This guide covers everything you need to know to get started with color by number as an adult.
Why Color by Number Works for Adults
Color by number removes the most anxiety-inducing part of coloring: deciding which colors to use. For many adults, that moment of staring at a blank page and wondering “what color should this be?” is enough to make them put the book down and scroll their phone instead.
With color by number, the decisions are made for you. Each section has a number, and each number corresponds to a color. You simply match the number to the color and fill in the space. This removes what psychologists call “decision fatigue”, the mental drain of making constant small choices, and lets you slip into a flow state much faster than with open-ended coloring.
A 2023 study on structured creative activities found that participants who followed guided coloring formats reported significantly lower anxiety levels than those who chose their own colors. The structure, it turns out, is the feature, not the limitation.
The Mindfulness Angle
Color by number is uniquely mindful because it gives your brain exactly one thing to focus on: matching the number to the color and filling in the space. There is no wondering if your color choices look good. There is no comparing your work to the example on the cover. There is just the repetitive, satisfying act of coloring within a system.
This makes color by number particularly good for people who struggle with “coloring anxiety”, that feeling of wanting to color but being paralyzed by the fear of making ugly color choices. If that sounds like you, color by number is the gateway drug into the wider coloring world.

Choosing Your First Color by Number Book
Not all color by number books are created equal. Here is what to look for when choosing your first one.
Large Print vs Intricate Designs
Large print color by number books have bigger spaces to color, which means less precision required and faster visible progress. They are ideal for beginners, people with hand pain or arthritis, or anyone who wants a more relaxing experience. The 2026 Color By Number Coloring Book: Large Print is a solid choice, it features large, readable number labels and simple designs that are perfect for getting started.
If you want something more challenging, the Creative Haven Around the World Color by Number book offers detailed travel-themed illustrations with smaller numbered sections. Creative Haven is a trusted brand in adult coloring, and their color by number series is consistently well-reviewed.
Color Key Format
Look for books with a clear, easy-to-read color key printed on each page (not just on the back cover). Some books put the full color key in the front of the book, which means you have to flip back and forth constantly. Others print a mini key on each page, much more convenient.
Number of Colors
Most adult color by number books use between 10 and 30 colors. Books with fewer colors (10-15) are simpler and require a smaller pencil set. Books with 25-30 colors produce more vibrant, realistic results but require a larger investment in supplies.
The Best Colored Pencils for Color by Number
Color by number books typically require a wide range of colors, often 20 or more. This means your typical 12-pencil set will not cut it. You need a set with enough colors to match the book’s palette.
The Crayola 100-Count Colored Pencil Set is the best value option for color by number. With 100 colors, you will always have a close match for any number in the book. Crayola pencils are soft enough to blend smoothly but firm enough to hold a point for filling in small numbered spaces.
If you want higher quality and more vibrant color laydown, the Faber-Castell Jumbo Grip pencils are excellent for larger-spaced designs, while the Prismacolor Premier 72-color set (already a ColoredCalm favorite) gives you premium pigment quality with enough shades to handle almost any color key.

How to Get the Most Out of Color by Number
Organize Your Pencils First
Before you start coloring, sort your pencils by color family (reds together, blues together, greens together). This sounds obvious, but it saves enormous amounts of time. When the color key says “number 14 is light blue,” you want to be able to grab that pencil without searching through 30 others.
Some color by number enthusiasts label their pencils with small sticky tabs matching the book’s numbers. This takes 15 minutes upfront but saves frustration over the entire book.
Work in Sections, Not Colors
A common beginner mistake is to fill in all of one color first, then move to the next. This works but it is boring and makes it hard to see progress. Instead, work section by section, complete a quadrant or a feature (like a single flower or building) before moving on. This gives you the satisfaction of seeing the image come together faster.
Do Not Be Afraid to Deviate
Here is a secret: the color key is a suggestion, not a law. If you do not have the exact shade the book calls for, use the closest match. If you think a section would look better in a slightly different color, change it. The point is to enjoy the process, not to produce a pixel-perfect replica of the cover.
Color by Number vs Free Coloring: Which Is Better for You?
Both formats have their place. Here is a quick comparison:
| Aspect | Color by Number | Free Coloring |
|---|---|---|
| Decision-making | Minimal, colors chosen for you | Full, you choose every color |
| Anxiety reduction | Excellent for anxious colorists | Can trigger “blank page” anxiety |
| Skill required | Beginner-friendly | All levels |
| Creative freedom | Limited but structured | Total freedom |
| Best for | Stress relief, beginners, winding down | Creative expression, practice, exploration |
Many colorists keep both types of books on hand, color by number for low-energy days when they just want to relax, and free coloring for when they feel creative and want to make their own choices.
Color by Number for Specific Goals
For Sleep
Color by number before bed is an excellent wind-down activity. The structured, repetitive nature requires just enough attention to keep your mind off the day’s worries, but not so much that it wakes you up. Keep the colors soft and the lighting warm.
For Focus and ADHD
For people with ADHD or focus challenges, color by number provides external structure that reduces the cognitive load of open-ended tasks. The clear rules (match the number, fill the space) make it easier to start and stay engaged without getting overwhelmed by choices.
For Recovery and Rehab
If you are recovering from injury, surgery, or a period of illness, color by number is a gentle way to rebuild fine motor skills and hand-eye coordination. The numbered sections give you clear boundaries, which helps you practice control without the frustration of trying to stay inside free-form lines.
A Starter Kit for Color by Number
If you want to try color by number without a big investment, here is a minimal kit:
- 2026 Color By Number: Large Print, beginner-friendly designs with clear numbers
- Crayola 100-Count Colored Pencils, enough colors for any color key
- Easy Coloring Book: Large Print Designs, a second book for when you want simpler patterns
That is under 35 dollars for everything you need to start. When you are ready to upgrade, add a Prismacolor 72-color set and one of the Creative Haven color by number books for more detailed designs.
Bottom Line
Color by number for adults is not a lesser form of coloring, it is a different tool with different benefits. The structure removes decision anxiety, accelerates the path to flow state, and makes coloring accessible to people who find free coloring overwhelming. Whether you are a complete beginner or an experienced colorist looking for a low-pressure option for tired days, color by number deserves a spot on your shelf.
Start with a large-print book and a 100-color pencil set. Give it one session. If you find yourself saying “just one more section” at the end, you will understand why this format is taking over the adult coloring world.
