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.
