Display Different Matrix Options Based on Current Tab of Site?

Kind of just what it sounds like. I have Matrix Items that appear in different sections of my site and the client would like to be able to have different Matrix options show depending on what section (tab) of the site you're on.

For example, the site currently has a military section and the client would essentially like for the military colors of a product to only be available within that section. Anybody got any bright ideas on how to accomplish this?

If that's not possible, would there be a way to kind of "clone" an existing item, where different colors could be maintained throughout the separate tabs so that changes made to one item would be reflected in its corresponding "clone" (so we wouldn't have to enter everything twice, which unfortunately is currently our mostly likely option barring any brilliant forum suggestions...:D )
