Thanks! That's actually the default of Plasma's Oxygen theme, I just adjusted the color little bit. But I especially love 'metallic' feel of it though, that's why I love Enlightenment's aesthetics so much.
I miss the depth of gui elements from 2000s desktops. Flat UIs look good, but I’ve been noticing lately some things are just easier to distinguish from the GUIs of yore.
