The Brush reflects the current theme and accent color, and it's also used to shade empty-group jump list items. By default, the Brush matches built-in apps, but you can override that to suit your design needs using the Enabled and Disabled properties.

ListViewItemPresenter	Represents the visual elements of a ListViewItem. When developing for Windows 10, use ListViewItemPresenter instead of GridViewItemPresenter in your item container style, both for ListView and for GridView.
