Volkswagen Think Blue
For years, European automakers (mostly) have used the color blue to identify their eco-friendly vehicles and initiatives, forgoing the green emphasis on this side of the pond. We have Hyundai's Blue-Will, Mercedes' Bluetec and so on. Heck, back in 2007, advertising agency JWT predicted a lingo shift from green to blue in 2008. Green still rules the environmental word world, but blue is making its presence known.
