I used Gnome to modify the default ubuntu color scheme. the default Unity environment is too difficult to use and ugly to unload. All topics of ubuntu are in/usr/share/themes. The default topic is Ambiance, so you can enter the Ambiance folder. Cd/usr/share/themes/Ambiance/first enter the gtk-2.0 folder. Back up the gtkrc file. Sudo cp gtkrc. bak open the gtkrc file sudo vim the gtk-color-scheme in the first line starting with gtkrc is the default color scheme of the topic. This string contains the color scheme. You can modify the color code as needed. Here is a color code online selector. this is my solution: gtk-color-scheme = "base_color: # ffffff \ nfg_color: #000000 \ ntooltip_fg_color: #000000 \ n selected_bg_color: #86ABD9 \ nselected_fg_color: # FFFFFF \ n text_color: #000000 \ nbg_color: # EDECEB \ ntooltip_bg_color: # E7F3FD \ n link_color: # DD4814 "where the tooltip is where the mouse is, then the prompt box popped out. The above can be used to determine what the meaning is based on English. If you are not afraid of tossing, you can adjust it slowly. Save and go to the gtk-3.0 folder and modify the settings. ini file in the same way. This is my solution: gtk-color-scheme = "base_color: # ffffff \ nbg_color: # f2f1f0 \ fingerprint: #000000 \ n selected_bg_color: #86ABD9 \ ntext_color: #000000 \ nfg_color: # 4c4c4c \ n tooltip_fg_color: # ffffff \ nselected_fg_color: # ffffff \ nlink_color: # DD4814 \ n bg_color_dark: #3c3b37 \ login: # dfdbd2 "restart takes effect.
