Blue rooms.

A couple of weeks ago the New York Times ran an article that blue rooms can bring out peoples' creativity and imagination. http://www.nytimes.com/2009/02/06/science/06color.html?scp=1&sq=a%20blue%20room%20for%20creativity&st=cse
If you can't repaint your entire agency, you might want to consider this painting by Rothko. The particular Rothko shown here was recently auctioned in London and sold for 300,000 pounds less than the asking price. So a bargain. And I like the colors.
