Show HN: ColoringMagician – Generate custom coloring pages using AI
https://www.coloringmagician.com
Hey HN!I made ColoringMagician because I got frustrated trying to find specific coloring pages for my niece. She's a true painter, always complaining about how she'd draw it differently if it wasn't a very generic coloring page.
It's built using a custom model, with some tweaks to generate clean line art (turns out, making AI create consistently good coloring pages is trickier than I thought!). The most interesting part was figuring out how to convert complex images into something that's actually colorable.
Things I learnt along the way:
- Kids are brutally honest beta testers - Making prompt templates is trial and error - Gemini 2.0 Flash is amazing

But, a true "Create now" experience could have been awesome. The preview images on the homepage look clean, and I really wondered what the machine might come up with. (Just not at the cost of a signup/signin.)
