What theme is this?

Looks like Eminence (it's dark blue)

You better recheck your link, I don't see a black Theme....theres only 2 themes on the right side of page, one is " Darwin " and the other is by essorant, both have download links.
This is where your link takes me:

Well unless they changed the screenshot the blue one in the front looks like Vista Plus V2 by Adni18

Nevermind...I tried to edit out my comment ...too slowww

No he meant the image on the right side towards the top that has vista plus V2 and two other themes

I don't think Im seeing the same page as you are or its not loading . I'm only seeing an advert to purchase windowblinds that says : Vista Ready and has the top bars of 3 blinds displayed , other than that, I see a preview for Darwin blind and Nuage Redux.
Thats it. Hopefully your referring to the advertisement for windowblinds or Im stuck in WC Twilight Z one again.

I looked again and I think it's a subscriber only skin called WC Select. If your a Wincustomize subscriber you'll find it under "Subscriber Resources" on the Home page.

It's Noire.

Sorry for the confusion. It the black window where there are three different windows. Two are like blue and the other one is black. The black is the one in the middle. The picture is above the buy now or free trial links.

See my post above, #8.

Bebi is correct... and I was lookin forward to posting an answer, only to see she'd beat me too it!  Curses... foiled again.
