You can also do a simlar thing as Dave is suggesting with dialogs
and alerts.  If you have a 'dctb' resource with the same ID as a
'DLOG', then GetNewDialog will open color dialog window (on a color
machine) that has the default colors specified in the 'dctb'.  A
similar situation occurs for 'actb' resources matching 'ALRT'
resources when you call Alert (NoteAlert, etc.) on a color machine.
The entries in the 'dctb' and 'actb' resource are identical to the
'wctb' format described in IM volume V - Window Manager chapter.
