I am trying to find what I need to edit in a GTK theme (specifically Ambiance) to change the opacity of a cut file. A selected file is orange and when I cut it, it is a little opaque - I'd like it to be more transparent, so that it is easily distinguishable.
I've played around with the
/usr/share/themes/Ambiance/gtk-3.0/gtk-main.css but I haven't seen any difference.
Edit: I've created a
nemo.css file inside the apps folder, properly imported it at
gtk-main.css, but I can not find the variable I need to change.
