In the Theme Prefs section of the XSites Wizard, you'll find several color schemes that match the default background. You can choose one of these schemes from the drop‑down list under Color Options. If you want a color scheme that is all your own, you can change the various border, navigation and text colors as well.
When setting custom colors, you can see which part you are actually changing by hovering your mouse pointer over the description, such as Top Border Background or Background Graphic. The corresponding area of your preview to the left will flash as you move across the link.
To change the color, click the colored box to the left of the description and then choose the desired color from the palette. If you're a graphic guru, or your company requires a particular shade of a certain color, you can also type in the "HEX" number of the color at the top of the color palette.
