change the default Color scheme in Kubuntu Feisty before it is released, the default one is way to depressing

The colours of the default color scheme are way too depressing for enduser's eye. There is grey overdose and should be changed to something lighter/marrier. There is a Color scheme named Murrine-elegant @kde-look, you can see what I am talking about here: http://www.kde-look.org/content/show.php/Murrine+Elegant+Rounded+Kubuntu+Colours?content=46731

This scheme when used gives better visuality of the widgets and smoother/more fresh look overall
