How to set a custom text highlighting colour
Solution 1:
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.
