To change the header color, specify a color name (eg. steelblue) or a hexadecimal color code (eg. #4682B4).

If using color name, it must be one of 147 names supported by commonly used modern browsers or the target system browser

Click the Update button at the bottom to apply the change.

A server restart is required for the update to be applied. 

After the restart, it should take you to the default tab's first article.
