Here is my way on how to change the selected item colour on Ubuntu (14.04); the steps are as follows:
- To start off, we need to open dconf-editor (Press Alt+F2 and type dconf-editor followed by the enter key).
- Navigate to the following path: org > gnome > desktop > interface.
- Find the key called "gtk-color-scheme" and set the value to "selected_bg_color:#023C88" replacing the hex code with the value of the colour you wish to use (I used #ccc for light grey).
- Done!
