I use AuroraMint as my themes, but some colors mess up my opera.
When I use gnome-appearance-properties -> customize theme -> Colors, I only can found input boxes' text color here. But I still want change background colors in email list (opera use GTK theme here). Gui give only 4 group colors here, so poor.
GtkColorScheme=fg_color:#cbf6d4d4bf8c,bg_color:#311133332e14,text_color:#8713a9515723,base_color:#444f47474026,selected_fg_color:#f554ffffe666,selected_bg_color:#9797bfbf6060,tooltip_fg_color:#000000000000,tooltip_bg_color:#f5f5f5f5b5b5
I thought maybe some software can use mouse click to found out widgets under mouse point, for I does not know which widget is email list used (if I change gtkrc file).
