Control styling is an important feature in XAML and all controls that come with any framework based on it are subject to styling. Panorama is no exception to this and although it can be styled, it is not immediately obvious how to do it. For example, if we want to add background color to the panorama title and the panorama item header (similar to the Facebook app for WP7), changing the background for either control will not do the trick.
