Niche of the Week: 2025 Week 45

Let's test this format in the Guild.

Sometimes we all need some external ideas, a push to continue moving. For some, it could be a small step, but for others, it can lead to a breakthrough.

Once a week, I will search for a profitable niche, research and validate it, and share the distilled results with the Guild members. It will not be a perfect niche, but it will have potential to create a first book, to test some new ideas.

The niche of this week is: Monochrome Coloring Book.

Please pay attention to the attached image; open it at full size, and you will find many niche ideas and keywords.

And now the validation results:

Demand: Strong. A quarter of the listings qualify as “Winners,” which means new books can reach good ranks with few reviews.
Competition: Moderate. Only 4 market staples—manageable for a focused launch.
Obsolescence: Very low, suggesting most books in this niche continue to sell.
Pricing power: Weak. Nearly all titles are priced under $10, indicating low perceived value and limited profit margins.

Verdict: The niche shows solid entry potential but limited pricing potential. To make it worthwhile, a book here needs a premium hook (e.g., unique art style, print quality, or theme variation) to break above the $10–12.99 range.

Winners: 14 books (26.9%)

Obsolete books: 1 book (1.9%)

Market staples: 4 books (7.7%)
