Package contains 8 versions of gtk3,gtk2,metacity,unity,xfwm4 and openbox theme.To install themes, extract archive to /usr/share/themes. Gtk3 theme is for 3.10 version.Requirements for gtk3 theme is only gnome-themes-standard package.Requirements for gtk2 theme is murrine and pixbuf engines.Gtk3 theme has customizable color.You can setup any color you want,just open file settings.ini and change value of 'selected_bg_color'.IMPORTANT: Theme must be in /usr/share/themes in order to work color customization.
If you use mostly gtk applications you can use Flattastic themes. If you use a lot qt application it is recommended to use Flatastic-Light themes,because Flatastic theme has text color problems with qt applications. It is unsolvable. If you have some problems with Flatastic themes and gtk apps just send a bug report here,and I will try to fix it(do not send for qt apps).
