I was going to start working on my DGS dioramas, but somehow ended up working on a Blender extension for adding support for the OKHSL color space. These things just happen, I guess. It sounds almost reasonable.
I've been a big fan of OKHSL ever since I read https://bottosson.github.io/posts/colorpicker/ . It's available in Inkscape, and I implemented it in my own WIP pixel graphics editor, and I can't bear the thought of having to use Blender without it. Well, I could, but I really want to work on it today.
