title: How to change the background color of Meld?
body: <p>I have Linux Mint 17.3 Rosa - Cinnamon as OS, the desktop is Gnome, and the toolkit is GTK 3.10.8 and GTK 2.24.23.
  I would love to change the background of Meld to a darker color.
  I followed these instructions: <a href="https://wiki.gnome.org/Apps/Meld/DarkThemes" rel="noreferrer">https://wiki.gnome.org/Apps/Meld/DarkThemes</a>, and the outdated technique (with a /.gtkrc-2.0 file) changed the colors what Meld use, but not the white background color. There is no variable in it for that.</p>
  
  <p>I tried to create/change desktop themes as well, but I was not able to change the background of Meld (but I do not know anything about Linux Mint themes).</p>
  
  <p>Any ideas, how could I change it? </p>
