You would probably get a faster answer in the PCB Design forum. You would need to be running Allegro tools versions 16.01, or 16.2, then you can export and import colour parameters which will affect which colour is assigned to which object. In 16.0 you can only save the colour pallette rather than the colour assignments. If you are needing to save specific views, use View>Color View Save, these views will then appear in the Visibility drop-down.
