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: 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.
