Have duplicated the default theme 'dark' variation and copied to the 'light' variation as per bug #621 (http://bugs.zpanelcp.com/view.php?id=621) reports that currently there was no actual content on the light variation so I have duplicated the current dark theme and when I am able to play around and test the changes to the CSS (to create a light variation) of the theme I'll commit the changes and then close the bug.
