Blue

Washington, February 7: Worried about a tough test ahead? Or unable to focus on a knotty task at work? Do not fret, just switch to red. The color, usually associated with danger, can actually improve the brain's attention to detail, says a new study.

According to a recent research at the University of British Columbia's Sauder School of Business, color and cognitive performance have a veiled link. While red is connected to improved focusing power, blue can boost creativity.
