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
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"
@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.
