Alternatively, using `hi! link SignColumn LineNr` will ensure that styling the user has applied to the more commonly used line numbering column will match the sign column used by vim-gitgutter.
I hate it when plugins try to override my colorscheme, so I would highly discourage adding this to the plugin. To account for colorschemes that don't add colors for SignColumn without angering users, use the `default` keyword without the bang.
Some other things to consider: The sign column and line numbers are separated by the fold column. The default colorscheme has SignColumn and FoldColumn the same (Cyan or DarkBlue on Grey) and different from LineNr (Yellow or Brown).
AFAICT, this was technique advice specifically relevant to the parent post, the ongoing thread, and to improving folks experience with the tool in original post. To the anonymous downvoter: I give up. I have no idea what message you were trying to send.
