How to make my action bars black like in the picture ?

Hello guys I want to ask how to make my action bars to look black like in the picture ?
I play on Icecrown realm Wotlk 3.3.5a

I currently use Bartender4 + Buttonfacade.

Did you apply ButtonFacade to Bartender?
If not: "ESC" -> Interface -> AddOns -> ButtonFacade and activate the skin you like for your bars. Also, make sure you've activated the button grid in your bartender options.

I Don't know the name of this Skin, it's not included in the Buttonfacade addon.

I'd say it's Caith.

Yes, it's Caith, but the icons look different on the picture, they are somehow shinny.
