I am not entirely clear on what you are trying to do. Are you trying to change the color based on some common category? For example, all locations in USA use red and all locations in UK use green. Or are you trying to achieve truly page-specific coloring? If the former, look at what DZeP linked to. If the latter, take a look at Help:Infoboxes.
