That’s the great thing about OKLab, it makes this kind of design much easier and more accessible without having to resort to color appearance models like CIECAM16 or even just CIECAM UCS.

Beyond luminance, I’m also adjusting for uniform chroma as otherwise the colours still stand out to different degrees from the background, so that might have been one of the issues you ran into.

Your color scheme was actually one of the ones I looked into before making my own because it at least came close to what I was looking for — and while it was close, the perfectionist in me wanted to make it mathematically optimal once I’ve started to think about it in these terms.
