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."

Description

Mono Moment is a monochrome, one-color coloring book for adults, made for anyone whose mind never quite switches off. Instead of dozens of colors and decisions, you fill bold, simple shapes with a single pen. There is no palette to plan and no wrong way to do it, which is what makes it so calming for an anxious or overthinking mind.

Every one of the 65+ designs is printed on premium 160gsm paper with no bleed-through, and the book lies flat so you can color comfortably anywhere. It is a screen-free, ten-minute ritual for winding down in the evening, easing stress, and giving a busy brain one quiet thing to focus on.

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.

Why choose Mono-Moment?

Research shows that decision fatigue affects every aspect of our mental health. Other coloring books hand you 60 colors and call it relaxing. That's 60 more decisions at the end of a day that already had 35,000.
Mono-Moment removes the choice entirely. Our single-color approach transforms coloring from a stressful activity into a truly meditative practice.

Frequently asked questions

What is a one color coloring book?

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 over $24 ($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.

Picked by 3 out of 4 book readers

Customers said this monochrome coloring book is "weirdly calming" and effective for anxiety relief and better sleep. The single-color, bold-shape format eliminates decision fatigue, making it ideal for overthinkers and ADHD brains. Praised for thick paper, spiral binding, and being a screen-free ritual. Some noted the cover marks easily, pen runs out quickly, or expected larger size.

  • My mind goes properly quiet in a way it has not in a very long time. I am sleeping better.
  • Exactly what my therapist described. It genuinely helps me come back down.
  • Finally a hobby my ADHD brain can finish. One pen, bold simple shapes, and I can just start.
  • 5 stars: 110 (75%)
  • 4 stars: 27 (18%)
  • 3 stars: 9 (6%)
  • 2 stars: 0 (0%)
  • 1 star: 1 (1%)

I love the mono-moment coloring book. It's simple but very relaxing and the dual tip markers work well. Thank you mono-moment for helping me to relax every evening.

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.

My no phones after nine rule finally works

I made a no phones after nine rule for myself and needed something to do with my hands so I would not cave and start scrolling anyway. This has been the answer. A cup of tea, one pen, and ten or fifteen minutes of just filling shapes, and my mind goes properly quiet in a way it has not in a very long time. I am sleeping better and waking up less anxious, and I genuinely did not expect a colouring book to be the thing that did it. Already recommended it to two friends who both ordered theirs.

A quiet thing my mum and I now share

I bought this as a gift for my mum who has been very anxious since my dad passed, but I ended up ordering a second one for myself after trying hers because I did not want to hand it back. She rings me now to say she does a bit before bed and it helps her switch off from the worrying. For both of us it is the not having to decide anything that makes it work. It is a lovely, quiet, screen free thing to share even though we live hundreds of miles apart.

Lives in my desk drawer at work

I keep this in my desk drawer at work now. When I feel an anxious spiral starting mid afternoon, I take five minutes and fill in a shape or two instead of stewing on it or stress eating. It resets me just enough to get through the rest of the day without that wound up feeling trailing me home. My wife has started stealing it in the evenings so I think we are going to need a second copy soon. Simple idea, really well made, and it does exactly what it promises.

Ten minutes I can actually finish

Perimenopause has done a number on my focus and I have felt scattered for months. Most things I start I abandon halfway through because I lose the thread completely. This I can actually finish, and finishing something, anything, has done more for my mood than I expected it to. Ten quiet minutes that ask nothing of my memory or my decision making. The spiral binding lays completely flat as well, which sounds minor but makes it so much easier to use without wrestling the pages down.

Kids see me relax for once

My children are used to me being on my laptop or phone. Now they see me sit and color quietly and one of them asked to join. Unexpected little win for the whole house.

Assumed it was a gimmick, now a convert

I will be honest, I thought the whole one colour thing was a bit of a marketing gimmick and nearly sent it back after it arrived. Then I sat down with it one rough evening when my head was going a hundred miles an hour, and I completely got it. The lack of choices is the entire point. There is nothing to decide and nothing to overthink, you just fill the shapes and your brain slowly goes quiet. Two weeks later it lives on the arm of the sofa and I would be genuinely annoyed if I lost it.

G

Exactly what my therapist described

My therapist actually suggested finding a low pressure, low stimulation activity to help with my anxiety, and this is exactly what she was describing without either of us knowing it existed. There is no comparing myself to some perfect result, no decisions to spiral over, just something steady and repetitive to do with my hands. I reach for it when I feel the tightness starting in my chest and it genuinely helps me come back down. It has become a real tool for me, not just a hobby I do when I am bored.

The one thing I can manage on no sleep

I am a new mum and my brain is basically mush from the broken sleep. I cannot follow a show, I cannot read a book, but I can fill in a few shapes while I feed the baby or during those strange quiet twenty minutes when she finally naps. It is the one thing in my day that is just for me and does not need a functioning brain to enjoy. My partner has noticed I seem a bit more like myself in the evenings since I started. Worth every cent for that alone.

Learn more about the book

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.
