Using/Modifying Built-In Theme Colors in WPF

[Drew]

Does anyone know where I can find some examples &/or resources on how to properly change colors for built-in themes?  I am trying to transition from using the Metro theme in which I had a singleton and could just access it and change the colors for the whole application.  To know I am trying to utilize the Windows8Touch theme and I no longer have access to something like: Windows8TouchColors.PaletteInstance.MainColor = Colors.Orange

[Drew]

Nevermind I found it:

Windows8TouchPalette.Palette.MainColor = Colors.Orange;
