culori

This looks fantastic for working with colors, and from a great developer too. A very very similar js library is Culori [0, 1], which I discovered on the original Oklab introduction post [2]. If you're doing generative artwork or any procedural work with a non-fixed palette, a good color library and working in linear or Oklab based colorspace is a must. Using sRGB or HSV/B when interpolating for gradients or generating palettes or complementary colors is extremely painful; a 50% brightness (HSV) yellow is visually much brighter than a 50% brightness purple, with similar issues cropping up for saturation. Balancing the lighting and contrast of programmatically generated colors is so much simpler when you have a perceptually uniform colorspace like OkLCh, or linear RGB if you're working with predefined hex values.
