eLuna is a GTK+3 theme that comes with a dark style and colored text (like for instance, blue text on the Unity panel/topbar).
eLuna brings a dark sidebar for Nautilus, as well as rounded search fields (in Nautilus), metal-like ON/OFF buttons, as well as various eyecandy bits.
The theme is properly integrated into Unity, thus displays its close/minimize/maximize buttons on the Unity panel when in fullscreen mode.
