Registering Your Own Magento Admin Theme

If you quickly need your own admin theme (skin), for example to replace the logo in the admin area or adjust some CSS to better match the customer's corporate identity, you can do this quickly with a simple configuration entry in your own module's config.xml or in the global local.xml.

<?xml version="1.0"?>
<config>
    <stores>
        <admin>
            <design>
                <theme>
                    <default>mytheme</default>
                </theme>
            </design>
        </admin>
    </stores>
</config>
