I applied a similar idea in a drawing application I wrote recently. You can paint and fill with 1-bit patterns, but since the underlying representation preserves a "color" index for each pixel, you can repeatedly flood fill, post-hoc edit patterns, and even animate the patterns: https://beyondloom.com/tools/ditherpaint.html https://beyondloom.com/tools/ditherpaint.html

What you've written is beautiful. I love that I'm drawing an image where the paintbrush behaves as an eraser.

This is great! I also get Classic Macintosh vibes from it. In fact, another of my projects is to use Classic Mac 1-bit drawing apps under emulation on an iPad Pro. Painting with dither patterns is so satisfying! I've done a few fine-art style pieces with this technique. https://blog.gingerbeardman.com/2021/04/17/turning-an-ipad-pro-into-the-ultimate-classic-macintosh/ https://blog.gingerbeardman.com/2021/04/17/turning-an-ipad-p...
