In details:

After setting for each selection a color, the vtkAppendSelection filter triggered will generate a new array vtkUnsignedCharArray for each SelectionData named vtkSelectionColor. Then the vtkExtractSelection will add this new array on the data and set it as color array.

vtkAnnotateSelectionFilter: new filter to labelize a dataset based on a selection

This filter will add a vtkStringArray on the dataSet as point or cell array (depending of the field type of the selection), user can set for each SelectionNode of the selection a label used in this array.

Note that we create a custom widget to associate for each selectionNode an value.
