One Color Coloring Books®
Bold designs made to be filled with a single pen. Thick 160gsm paper, metal spiral, rated 4.7/5 by 163 readers.
One color coloring books strip the hobby down to what actually calms you: bold black designs, a single pen, and zero decisions. No 72-pencil palette to manage, no color theory, no planning. You pick one color for the page and let your mind go quiet. Also known as monochrome coloring books, they are printed on thick 160gsm no-bleed paper and finished with a lies-flat spiral.
Whether you searched for a single color coloring book, a monochrome colouring book or a one colour colouring book, it is the same idea: one pen, one page, no palette. It is the format 10,000+ overthinkers use for 20 quiet minutes a night, and every book ships free with a 60-day money-back guarantee.
Which one color coloring book should you start with?
The Original Edition is the one to begin with: 65+ hand-drawn scenes and quote pages with big, bold shapes you can finish in an evening. Already colored it cover to cover? The New Chapter Edition continues the ritual with all-new pages built around fresh starts. Both pair with our dual-tip brush pens: a broad end that fills big shapes fast and a fine tip for clean edges.
What makes a one color coloring book different
Your brain makes about 35,000 decisions a day. A traditional coloring book adds dozens more per page. A one color coloring book removes the choice entirely, which is why so many overthinkers find it easier to stick with. Every page is printed on thick 160gsm paper, so markers and brush pens will not bleed through, and the metal spiral lets the book lie flat while you fill. Curious about the idea behind it? Read what monochrome coloring is and why paper weight matters.
Frequently asked questions
Is one color really enough? Yes. Removing color decisions is precisely what makes the format restful. Most readers use plain black ink.
What pens work best? Any water-based marker or brush pen. Our dual-tip pens are tuned for the 160gsm paper: full coverage, no bleed-through, no ghosting.
Is a one color coloring book good for anxiety or ADHD? Many readers pick it precisely for that: fewer decisions means less friction to start and an easier time staying with the page. Read why one color works for ADHD brains.
Will markers bleed through the paper? No. Every page is 160gsm, single-sided-friendly paper: brush pens and water-based markers stay on the page, with no ghosting on the back.
Can I give it as a gift? It is one of our most gifted items: the black cover, the spiral and the one-pen idea make it an easy present for an overthinker. See our stress-relief gift guide.
How long does a page take? Most pages take one quiet evening, not a month. Big shapes fill fast, which is why these books actually get finished.
Which One Color Coloring Book® is for you?
Original Edition
Where it all started: 65+ bold designs — botanicals, objects and typography — printed on 160gsm paper with a metal spiral. The right first book.
New Chapter Edition®
The second book. New designs built around fresh starts and closing chapters, same one-pen calm, same no-bleed paper. For finishers of the Original — or gifters.
3 Dual Tip Brush Pens
The companion set: brush side fills bold shapes fast, fine tip catches the edges. Rich black ink, tested on our paper — $5 instead of $9.95 with any book.
One page, one pen, zero decisions
Why one color changes everything
A classic adult coloring book hands you a decision every few seconds — which pencil, which section, do these shades work together. That decision load is exactly what an overthinking mind doesn't need at 9pm. Our one color coloring books remove it entirely: every page is a set of bold black designs made to be filled with a single pen, so the only thing left to do is the calming part.
Both editions are printed on premium 160gsm paper — roughly twice the weight of a standard coloring book — so brush pens and markers never bleed through, even printed on both sides. The metal spiral means the book lies flat on your lap, on the sofa, in bed. Details matter when the whole point is friction-free calm.
