306 Prompts for Monochrome Coloring Books:
The Lazy Way to Publish Coloring Books That Sell!
Hey everyone, it’s Ethan here.
A few months ago I picked up 306 Prompts for Monochrome Coloring Books by Paulo Gro right before it officially launched, and I’ve been using it consistently since then. I decided to write this honest review because I know how many “AI prompt packs” are out there that sound amazing but deliver very little in real life. So here’s exactly what I’ve experienced.
What Is 306 Prompts for Monochrome Coloring Books?
306 Prompts for Monochrome Coloring Books is a collection of ready-to-use ChatGPT prompts that instantly generate high-quality, print-ready monochrome coloring pages with a unique soft-gray coloring area system. Each prompt creates a clean, bold, stencil-style page that looks polished and professional straight out of the AI — perfect for Amazon KDP, Etsy printables, and digital downloads.

306 Prompts for Monochrome Coloring Books Review: My Experience After Using It for Several Months
I’ve been running a small KDP publishing side hustle for a couple of years, and monochrome coloring books were always something I wanted to try but never had the time or design skills for. After getting these prompts, everything changed.
In the first month alone I created and published four 40–50 page books. The soft-gray guide system is genuinely brilliant — pages look premium right away, and buyers immediately understand where to color. No more guessing or fixing messy AI outputs. The quality is consistent across all 51 categories.
After several months of regular use, I now have a growing catalog that sells every single day with almost zero maintenance.
306 Prompts for Monochrome Coloring Books Review: How It Changed My Workflow and Boosted My Results
The biggest win for me has been time. What used to take me days (sketching ideas, testing prompts, fixing contrast issues) now takes minutes. I can generate a full set of pages for a new book in one focused evening.
Because of that speed, I’ve been able to publish much more frequently. My monochrome coloring books are now bringing in an extra $2,800–$3,400 per month in passive income. That’s on top of my other KDP titles. One cozy reading nook book in particular is doing almost $900/month by itself. The combination of the gray-guide pages + the 4 bonus prompts (especially the dotted and reverse coloring versions) lets me create multiple product variations from the same scene, which has massively increased my catalog depth and revenue.
