Welcome to Machina Mono

We're a small team creating bold, monochrome coloring books.


Each design is made to be filled in with just one black pen or marker.


No color choices, no stress. Just you, a pen, and clean lines to fill. Simple, relaxing, and satisfying.


Get a free coloring page every month.


Sign up for our newsletter and we'll send you a new design to fill in, plus updates on new books and behind-the-scenes bits.
