Remember that these proposals are vying for a place on a default install/community themes package but not as the default theme.
The blurb has this to say about the theme: –
“Ubuntu derived theme with subtle gradients and lighter colors based on a loose interpretation of the new look of Ubuntu’s Single Sign On.”
An interesting choice to derive colours from – one that, in theory, should provide the colour palette for Lucid’s new ‘light’ theme.
Note that it requires the latest Murrine engine to function properly.
