Where can I know key of Windows 8 metro background brush?

Question

It is kinda baby question but it is important for the visual appearance of my app.

When I installed Windows 8 DevPreview on my PC os proposed me to choose the color scheme for Metro UI. I preferred teal color. It is something like next:

So I have this color scheme for background and for setting background. Now I want to implement the custom setting for my app. Something like next:

But for good user experience, I want to keep my settings in the same color that system. In the current moment, I set settings background manual. But it isn't a solution because a user can prefer another color scheme. I've checked in StandardStyles and in main generic XAML file. But looks like that I missed it. I would be pleasure if anybody help with this.

This value is not available in the current SDK. Though the initial settings flyout pane does match the system color, you'll notice that any custom settings panes are usually white or a color that matches the application.

Take a look at the Bing Weather app and you'll see what I mean. All of the applications custom settings have a blue background (even though I personally have a teal theme).

Also, don't get confused by the "Permissions" settings. That dialog is also provided by the OS.
