Currently the Admin page is identical on all instances. It is possible to change this manually by altering the .jar files, but that's very sub-optimal (for one thing, they change with every new install).
Within the web-core-x.y.z.jar there is a file - org\geoserver\web\css\geoserver.css
Changing the #header "background: #fff;" (line 227/228) value to something else results in the header bar changing colour. This is a very effective way of allowing a admin to determine which server they are on in a multi-server environment.
Provide a simple way for the user to alter this header background colour.
Ideally within the file that stores this, the colour would be associated with the URLort of the instance (or some other unique-per-instance factor), so even multiple servers using the same GeoServer_Data_Dir can have different colours.

<p>Ok, so JIRA isn't letting me add my screenshots.</p>
