Nice work ... really like these! Personally, I could see myself tweaking the palettes to have a bit more saturation and maybe even have a particular hue palette or have the hues centre around a particular value as you do with the "warm" variant or the "Zenburned" (my fav, and similar to my own manual scheme) in the showcase (https://github.com/mcchrish/zenbones.nvim/blob/main/doc/show...). Interesting to compare to the the parent post as luminance/brightness contrast based perception is generally better than our colour contrast based perception. There's arguably less information, as colours are categorical (not continuous like brightness) and colours multiplex brightness with hue and saturation, but there are probably some pretty objective metrics in which your kind of scheme would tend to be better in readability.

Very interesting to see this, because a few days ago I started using a theme that takes the complete opposite approach: limited hue range, but wide luminance range. https://github.com/mcchrish/zenbones.nvim I've found it to be quite practical because it makes keywords easier to pick out, and it allows search matches and diagnostics to stand out better.
