Parenthesis not visible in comments when matching brackets are highlighted

This is happening because the color of the comments is the same as the matching parenthesis highlight color. This makes using brackets a little difficult in the comments.

Possible solution:
Set the 'MatchParen' highlight group's guibg to a lighter shade.

:h hl-MatchParen

You could change the colors to fix it. This is my config:

require('onedark').setup {
    style = 'dark',
    colors = {
        grey = '#868686', -- Comments
        light_grey = '#a3abbf',
        bg3 = '#1e1e2e'   -- Selection
    }
}
require('onedark').load()
