We do not have such list. If the tree view has a ButtonChrome you can check what bindings are on the ButtonChrome and see what brushes are used in the corresponding states. In general the best solution would be to inspect the XAML of the ControlTemplate and see which brushes are used by the desired states.
We have tried to put self explaining names on the brushes but since same brushes are used in various states and different controls we ended up unable to provide a perfect solution.
