Hello,

The Metro-Style Window demo in the Themes area shows how WindowChrome can add any content to the title bar, keeping the rest of the title bar as-is.  RibbonWindow (I assume that's what you mean here) does use WindowChrome behind the scenes, but you can't declare another instance in XAML like you can in that demo since that would wipe out the internal one we use.  Instead you'd have to call WindowChrome.GetChrome(window) in the window's constructor after InitializeComponent.  Then you could programmatically set its chrome.TitleBarContentTemplate property to a DataTemplate you grab from Resources and that will let you add custom title bar content to RibbonWindow.

Title bar backgrounds are done like this in the RibbonWindow template:

{DynamicResource {x:Static themes:AssetResourceKeys.WindowTitleBarBackgroundActiveBrushKey}}

If the window is inactive, it uses the WindowTitleBarBackgroundInactiveBrushKey resource instead.  To alter those, you could probably place new values for those resources in your window's Resources.  Since they are referenced with a DynamicResource, the new values should flow down.
