LSP float text not visible in light mode with high contrast variant

[laurentS]

I'm using this theme with neovim 0.8.x from the nightly releases and alacritty as my terminal.

Overall it looks neat, but I have an issue with the LSP completion (I use https://github.com/hrsh7th/nvim-cmp/ for autocompletion) floating list of suggestions which are "invisible" in light mode. Dark mode works well.

My config is as shown on the screenshots above, and I have:

vim.o.termguicolors = true
vim.o.background = 'dark'

in my init.lua (I toggle the background value to light as needed).
Any tips on what might be causing this? I haven't managed to figure out which element in the theme I need to change to fix this, but happy to send a PR if someone can point me in the right direction.
This only happens with solarized-high, the other variants work fine.

These are the highlight groups in nvim-cmp documentation can you play with these and see which works out ?
