In order to change the navigation pane's default color of white, an unsafe change must be made to a file on the server. Please note that this change will cause file validation failures when updating the Portal Framework through Expressway and will have to be reverted back. Make sure to take a copy of the file first!
1. On the Passageways Application Server, navigate to the portal installation directory.
ex.) Drive:\inetpub\wwwroot\Production Portal
NOTE: The portal's folder naming convention will vary.
2. Make a copy of the PortalNavigation.aspx file.
3. Open the PortalNavigation.aspx file.
4. Find the <body class="portalbodytext"> line
Change it to say,
<body class="portalbodytext" style="background-color:#xxxxxx">
#xxxxxx is the Hex code for the color you want the background to be or the color word that represents the color.
5. Save the file.
