GetSimple allows developers to customize the colors within the administrative panel - effectively “branding” the control panel.

Tips to a good and working admin color scheme:

1. Place the file as admin.xml inside the folder /theme/
2. There are a couple images within /admin/template/images that might need to change as a result
3. Colors need the hash in front of the hex value. eg: #333333
4. Do not use shortcut hex values. eg. #333

The format of admin.xml is:

<?xml version="1.0"?>
<item>
	<title>Admin Skin Name</title>
	<author>Your Name</author>
	<link>http://www.yourdomain.com/</link>
	<primary>
