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 50 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.

The research behind this book
Three published studies shaped the one-pen, one-color format. Here they are, with links to the journals.
Coloring a structured design for ~20 minutes significantly lowered anxiety (measured with the State-Trait Anxiety Inventory). Free-form drawing did not.
Independent replication, seven years later: structured coloring again reduced anxiety significantly more than free drawing.
van der Vennet, R., & Serice, S. (2012). Can coloring mandalas reduce anxiety? A replication study. Art Therapy, 29(2), 87–92. doi.org/10.1080/07421656.2012.680047
Across 1,112 court rulings, favorable decisions fell from ≈65% to nearly zero as judges made decision after decision, recovering after each break. Decision fatigue is real — this book asks you to make zero of them.
Danziger, S., Levav, J., & Avnaim-Pesso, L. (2011). Extraneous factors in judicial decisions. PNAS, 108(17), 6889–6892. doi.org/10.1073/pnas.1018033108

Why choose Mono-Moment?
ResearchDecision fatigue: Danziger, Levav & Avnaim-Pesso, PNAS (2011) · sequential decisions measurably degrade the quality of our judgment through the day. Structured coloring: Curry & Kasser, Art Therapy: Journal of the American Art Therapy Association (2005) · structured colouring reduced anxiety significantly more than free drawing. Read the PNAS study · Read the Art Therapy studyi 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.

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: 50 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?
Water-based pens. Our dual-tip brush pens are made for this paper, and other water-based brush pens, fineliners and gel pens work well too. Every page is printed on both sides, so skip permanent and alcohol-based markers like Sharpie or Copic: they soak through to the design on the back.
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.

Such an amazing book! Seeing it was double sided I was afraid the pages would bleed through and they didn’t! I am over half way done with the book and every single page puts a smile on my face. I just love cats so much. I will be buying more books from you.

The colouring books are extremely addictive. You only need one pen which is great, saves the hassle of changing pens. I love seeing the picture come alive. And the other night I coloured in 4 pages. Stopped me from snacking which is good.

Genuinely the best colouring book I've used. The prints are super cute and using one colour means there is absolutely nothing to think about whilst colouring in. It's definitely helped me relax in the evenings and has cut down my doomscrolling hours. I can't wait to buy more books (roll on Halloween collection!)

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.
