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).
