A background is the underlying color, picture, or pattern that you see on a Web page.
Many backgrounds are interesting, but make it very difficult to read the text.
Be sure you choose a background that makes it easy for your viewers to read your text. When you are in Composer click on the Format button, then choose the Page Colors and Properties option. The Colors and Background dialogue box that you see below will appear and offers three choices. To choose a color click on the Background button and a palette of colors will appear. You can choose from these colors or click on Other and you have many more choices.
