The PersistenceFramework is not persisting the bindings. It only saves and loads the local values of the controls. In your case, the PersistenceFramework would save the Background of the ColorPicker and then restore it. Are you using OneWay bindings? Please note, that with the one-way binding, when the source's local value is updated, the binding deactivates and the target stops updating. If this is the case, try using a two-way binding.
All the best,
