The intricate ones stressed me out, this does not
"Too many tiny sections, too many decisions about which colour goes where, and I would give up feeling worse than when I started. This is the complete opposite. Bold simple shapes, one single colour, and actual calm. I finally understand what people mean when they say colouring helps them."

Is this for you?
If your brain is still running at 10pm when you just want to rest… If you've downloaded three meditation apps and abandoned all of them by week two… If you own coloring books that stressed you out more than they helped…
Then yes - The Original Monochrome Coloring Book by Mono-Moment was made for you.
Your evenings get a different ending:
🫖 Make the tea, settle into the chair 🎧 Put on something quiet, lo-fi, jazz, or your comfort show 📖 Open to any page, the order doesn't matter 🖊️ Pick up one pen, one color 🧠 Let your hands move while your mind finally stops
No decisions. No matching. No wrong answers. Just you, the paper, and twenty quiet minutes of doing one thing.
How does it work?
This isn't a regular coloring book. Everything that usually makes coloring stressful has been removed by design.
One color. That's it. No palette to plan. No shades to coordinate. Pick up one single pen (black, prefered but can be your favorite color) and start. The illustration is designed to work in any single color.
The image reveals itself as you go. The page starts as a network of lines you can't quite read. As you color, the scene emerges : a botanical, a still life, a slow afternoon. You won't know what it is until you're halfway in. That's the point: no planning, just presence.
Twenty minutes is all it takes. Each illustration is designed to be completed in one sitting. Because finishing something - anything - feels good. And after a day of 35,000 decisions, your brain deserves a small, quiet win.
One outline, one pen. That is the whole method.

A one color coloring book (also called a monochrome coloring book) is an adult coloring book designed for one single pen. Instead of choosing between dozens of colors, you fill bold, flowing designs with just one color, which turns coloring into a calm, decision-free ritual. Our One Color Coloring Book is the original: 65+ bold illustrations on thick 160gsm paper, made to quiet an overthinking mind.
Won't it be boring with just one color?
Surprisingly, no. Removing color decisions lets you focus entirely on the meditative act of filling in shapes. Most customers tell us it's more relaxing precisely because it's simpler. Your brain wants boring right now—trust us.
What kind of pens work best?
Any pen you love. Our 160gsm paper handles markers, gel pens, fineliners, and even light brush pens without bleed-through. We recommend water-based markers (like Tombow or Crayola SuperTips) for the smoothest experience. Avoid alcohol-based markers like Copics.
How long does one illustration take?
Most illustrations take 15-30 minutes—perfect for an evening wind-down or a lunch break. We intentionally designed them to be completable in one sitting, because finishing something feels good.
Is this good for anxiety?
Multiple peer-reviewed studies show that 20 minutes of structured coloring significantly reduces anxiety. It calms the amygdala (your brain's stress center) and promotes flow states similar to meditation. That said, we're a coloring book, not a replacement for professional mental health support.
What's your return policy?
30-day returns. If you don't love it, email us and we'll make it right. No complicated forms, no attitude.
Do you ship internationally?
Yes! We ship worldwide. US shipping is FREE from $19 ($4.95 below), free over £19 in the UK and A$44 in Australia, free everywhere else. US orders arrive in 5-8 business days after dispatch, international orders in 7-14.

A single-color coloring book designed for relaxation and stress relief. Customers said it's "very relaxing" and "calming," praising the thick, high-quality paper that prevents bleed-through and spiral binding that lays flat. Many found it helpful for anxiety, ADHD, and sleep improvement. Some noted designs feel repetitive or too simple, while others appreciated the simplicity. Common concerns: included pens run out quickly, pricing seems high, and some prefer more design variety.

I've tried many of these colouring books but this is by far the best, the paper is really good quality, the pictures are just right and the pens last.
Will definitely buy again.

This coloring book is so fun to use. Everything has been thoughtfully done to ensure a premium and relaxing coloring experience. The pages are thick and don’t bleed through and the spiral bounded book makes it lay flat. The illustrations have fat lines and don’t require much intricate work to complete the drawing and make them really beautiful.

The intricate ones stressed me out, this does not
I have tried the intricate adult colouring books and they honestly stressed me out more than they ever relaxed me. Too many tiny sections, too many decisions about which colour goes where, and I would give up feeling worse than when I started. This is the complete opposite. Bold simple shapes, one single colour, and actual calm. I finally understand what people mean when they say colouring helps them. It just took the right kind of colouring book for my particular brain to click.

My new morning thing
I bought it for evenings but ended up using it in the morning with coffee. 10 minutes before I check my phone or emails. Helps me start the day not in reaction-mode. Husband thinks it's weird but he's already noticed I'm less snappy in the mornings, so.

For the brain that won't shut off
I have ADHD and a stressful job. My therapist suggested coloring as a regulation tool. I tried 3 mandala books and quit all of them — too many tiny shapes, too many decisions. This format is exactly what someone with ADHD actually needs. Big shapes, one color, no cognitive load.

Shipping was slow to the UK
The book itself is fine. But the shipping took 14 days to reach the UK which felt long for $25. By the time it arrived I'd lost some of the motivation that made me buy it. Would have given 4-5 stars if shipping had been quicker.

Beautiful as an object
I'm a designer and notice the aesthetic of everything. This book is beautifully made — the paper weight is real, the spiral binding is well done, the cover design is striking. I keep it visible on my coffee table when guests come over and people always ask about it.

Better than the meditation apps I've tried
Got this on a whim. I was skeptical because it's just one color and looks too simple. That's the point apparently. There's nothing to decide so my brain finally has a break. My husband thinks it's weird but I genuinely look forward to this 5 min every night now.

Took it to chemo with me
Bought this for the long chemo waits. Way better than scrolling my phone for 4 hours under fluorescent lights. The mindless filling is genuinely calming during a stressful time. My nurse asked where I got it.

Replacing TV before bed
Used to watch Netflix until I fell asleep. Now I do 5-10 mins of this with a tea and I'm calm by 10pm. Even my partner asked to try it. We now do 20 min together before bed (without phones obvs). Genuinely changed our evenings.

Works for ADHD too
I have ADHD. Most coloring books overstimulate me with all the detail. This one bold shape per page is the only thing that actually feels relaxing. Small sample size but if you have ADHD, this is it. Five stars.

It is helping slow down after years of my nervous system being on full alert, having been diagnosed with PTSD! I’ve tried various other things and ways to help myself in this area but I have not managed to engage with them. MONO MOMENT helps my slow down and helps me feel I’ve achieved, accomplished, created something artistic. I’ve tried lots of different things to be creative but I do not have the skill or ability, I’m simply just not an artist, but MONO MOMENT is a game changer

Book was great lots of detail,color does not leak through,but I havnt even made through half the book and markers are already dying
Thank you for this, for the kind words and for the honest note on the pens. Ink use varies a lot from page to page (depending on the illystration), which is why the 3-pen set is meant as a starting companion, and why the new 6 and 12-packs just landed 🤍

Why a single-color book
When you sit down with a typical coloring book, the first decision you make is not where to put the pen — it is which pen. That choice quietly cascades. You start comparing palettes. You worry about "ruining" a page. The point of coloring as a wind-down — not thinking — gets lost. Removing color from the equation removes the friction. You pick up one pen, you start anywhere, and the only signal your brain receives is follow the line. Research on coloring as a stress-reduction practice consistently finds that structured, low-decision drawing produces measurable drops in state anxiety within 15 to 20 minutes.
Specs
50+ original illustrations — botanical and abstract designs drawn for low decision fatigue
160 gsm cream paper, double-sided, no bleed-through with water-based pens
8.5" × 8.5" square format — large enough to relax with, small enough to travel
Soft-touch matte cover with debossed title
Lay-flat binding
Who it is for
People who lie awake running through tomorrow and need a wind-down that is not a screen
Anxious or overstimulated minds — coloring quiets the verbal-analytical loop without asking for input
Adults who tried other coloring books and found them too busy, too colorful, too much
People who travel and want a pocketable mindfulness practice
Anyone giving a meaningful, screen-free gift
What pens to use
The 160 gsm paper is engineered for water-based pens. Recommended: brush pens (Tombow Fudenosuke, Pentel Pocket Brush), fineliners (Sakura Pigma Micron, Staedtler), gel pens, colored pencils. Avoid alcohol-based markers like Copic — they will bleed through any printer paper.
One pen. No color choices. No perfectionism. Just twenty minutes of quiet for a mind that never stops. One color coloring books for everyone.
