Thanks, I'll look into it

Thanks a ton for this amazing color scheme @shaunsingh - would love to use it, but this is now on main and unfortunately the thing that keeps me from using oxocarbon vs tokyonight or others that already support it.

Yep, this would be great!

I think for this one would "only" need to define all of the @lsp.* colors, that can be viewed using :highlight. See here for reference: https://github.com/folke/tokyonight.nvim/blob/161114bd39b990995e08dbf941f6821afbdcd666/lua/tokyonight/theme.lua#L266
