I am just getting into vim and I'm trying to get the preview window for my Rg results to show up with nice looking colors. Currently I have most of the stuff looking nice; here is a picture of where I currently am:

enter image description here

This is in my vimrc for how I setup the Rg with quickfix window:

  command! -bang -nargs=* Rg
    \ call fzf#vim#grep('rg --smart-case --line-number --no-heading -- 
      color=always --colors "path:fg:93,169,245" --colors 
      "line:fg:128,128,128" --colors "match:fg:195,232,141" --no-hidden 
      -- ignore '.shelles    cape(<q-args>),
    \ 0,
    \ fzf#vim#with_preview({'options': '-e --delimiter : --nth 3..'}),
    \ <bang>0)

What settings could I tweak in order to get the preview window to be consistent with the normal text in the editor? Any help would be appreciated.

    I would suggest you to use leaderf(plugin like fzf) with popup window, it looks the same as original. I haven't tried with rg, only with lines. I tend to believe it works.

    I wonder if it’s not all the color settings you’re passing to rg? I don’t know fzf all that well, but it can be difficult to properly color text thats not going to an actual terminal (eg when its being captured into a file/by a function call)

If installed, fzf vim uses bat to add syntax highlighting to the preview. bat comes with several themes available. You can choose a theme by setting the BAT_THEME environment variable. For example, you can add this line to your .bashrc or .zshrc to set the TwoDark theme:

 export BAT_THEME="TwoDark"

To preview the available themes run in your shell:

bat --list-themes

You can also add your own themes in case you are not happy with the available ones (as explained here).
