{
    styles = {
        transparency = true
    }
}

before_highlight

{
    before_highlight = function(group, highlight, palette)
        -- Disable all undercurls
        if highlight.undercurl then
            highlight.undercurl = false
        end

        -- Change palette colour
        if highlight.fg == palette.pine then
            highlight.fg = palette.foam
        end

        -- Change palette colour for dark variants
        if vim.o.background == "dark" then
            if highlight.fg == palette.pine then
                highlight.fg = "#3e8fb0"
            end
    end,
}
