Deus Ex: Human Revolution - Why Black and Gold?

We've seen umpteen interviews on the Deus Ex: HR art style but CVG finds out why it's black and gold.  Because of an ad!

"Okay, so that was just one day... one picture. I think it was like a Sunday, and I saw this black and gold advert - I have no idea what it was. But it just struck me - this could be a great palette, it's never really been used in videogames. It was great for communication, packaging, bags so on," Jacques-Belletête explained.
