Anyone Running a Coloring Pages Site?

Hey everyone, I’ve been looking into the coloring pages niche and wondering if anyone here is actively working on a site like this. How are you generating your content/coloring pages: AI, hand-drawn, or sourcing from elsewhere?
Also, what are you seeing in terms of traffic trends, CTR, and monetization (AdSense, affiliate, etc.)? Is this still a profitable space in 2025 or too saturated now? Would love to hear about your experience or any tips for breaking in.
