that the default values for each archetype color are provided previously, in RGB.
To initialize the preferences, we look to the generated DiagramPreference
Initializer class. We need to have the initializer call our initArchetype
Defaults() method, provided earlier, as shown in the modified implementation
here:

public void initializeDefaultPreferences() {
IPreferenceStore store = getPreferenceStore();
DiagramPrintingPreferencePage.initDefaults(store);
DiagramGeneralPreferencePage.initDefaults(store);
DiagramAppearancePreferencePage.initDefaults(store);
DiagramAppearancePreferencePage.initArchetypeDefaults(store);
DiagramConnectionsPreferencePage.initDefaults(store);
DiagramRulersAndGridPreferencePage.initDefaults(store);

}

These are the additions made to the org.eclipse.dnc.diagram.part.
