well, they do say blue is the new green

Ad agency JWT says blue will be the new green
Is Al Gore the bluest man on earth? Advertising firm JWT predicts that one of the top trends of 2008 will see blue replacing green as the color of environmentalism, social conscience, and all-round niceness. JWT notes that blue is the color of the sea and the sky, making it easier for people to identify it with the current hot-button issue of climate change.
