If you use the Adwaita theme you get Blue as the highlighting colour, for Numix you get Red/Orange (not sure exactly which), I have Numix, and like it, but I would like to change the highlighting colour (but not theme) to Green for a change, how can this be achieved? I am running Ubuntu GNOME 15.04 with GNOME 3.16.


The color code is #d64937

find "/usr/share/themes/Numix Daily/gtk-3.0" -type f -name '*.css' -print0 | xargs -0 grep 'd64937'

therefore you have to change two files:

sudo nano "/usr/share/themes/Numix Daily/gtk-3.0/gtk-dark.css"
sudo nano "/usr/share/themes/Numix Daily/gtk-3.0/gtk.css"

Search for

@define-color selected_bg_color #d64937;

And replace with

@define-color selected_bg_color #4A90D9;

Restart GNOME via Alt-F2 any type r isn't enough, logout and re-login.

  • this is no longer true since GTK 3.18+ because GNOME decided that CSS needed to be incredibly complicated so they compiled it into a custom binary called "gresource". GNOME makes silly decisions way too much. May 20 '17 at 3:50
