OK, if you create the 'Red' and 'Blue' character Styles as previously discussed, you could then run the following macro:
Code:
Sub RevisionColorize()
Dim i As Long
With ActiveDocument
.TrackRevisions = False
For i = .Revisions.Count To 1 Step -1
With .Revisions(i)
If .Type = wdRevisionDelete Then
.Range.Style = "Red"
End If
If .Type = wdRevisionInsert Then
.Range.Style = "Blue"
.Accept
End If
End With
Next
.Revisions.RejectAll
End With
End Sub
