Wrong color of signcolumn in shaded window

[wvffle]

My signcolumn is colored green for some reason. I'm using https://github.com/Shatur/neovim-ayu theme.

Weird. I honestly probably need to rewrite sunglasses, it has been a bit fucky lately and its code isn't exactly "intuitive" for PRs.

For the sake of completeness, can you upload a minimal reproducable configuration for me so I can reproduce this?
