My main objective was to have a hand-made color palette for my future NixOS setup. The problem is the majority of palette generators are so manual, simple. They work, but I wanted one that implements oklch. Yes, for my needs it's pointless but I'm bored.
Fortunately, that site exists (thanks @ardov!) and has a very nice set of features; BUT, at the moment I'm with lots of colors, it's very tedious to modifiy its parameters, like the chroma. However, in there it's possible to paste a .json-structured palette and test it easily. The only thing I'd to do was to generate it.
Parallelly, I wanted to see how smooth is programming with haskell + nix, so I've developed the .json generator with this lang.
Made with blood, sweat and tears, here is the pretty result I'll be using for now.
