How to modify the background color in Ubuntu 12.04

When I used 10.10, it was easy to set the background color to the eye-catching mung bean color. I recently upgraded 12.04 and found that the system did not provide a visual modification tool. So I started Google search, the solution was found on the UBUNTU Forum website.
First install dconf-editor,

 
Sudo apt-Get install dconf-Tools
 

Open dconf-editor, find org-gnome-desktop-interface, and find GTK-color-scheme. It is empty by default and needs to be written in by yourself.
The write format is:
Project name: color name;
Project name here you need to find the default colors in gnome in the http://live.gnome.org/GnomeArt/Tutorials/GtkThemes/SymbolicColors

Fg_color the base for the foreground colors. bg_color color to generate the background colors from. base_color the base color. text_color the text color in input widgets. selected_bg_color color for the background of selected text. selected_fg_color color of selected text. tooltip_bg_color background color of tooltips. tooltip_fg_color text color for text in tooltips.
 

This is what I set here.
Base_color: # cce8cf
Bg_color is generally the background of file browsing, and is generally a non-text background.
Base_color: the background of the text editing area.
Note: The following description may be a' \ n' separated list of "Name: color" as defined by the 'gtk-color-Scheme 'setting,
Here, we need to primarily use English ";" instead of "\ n"
