Time to break out the orange attire. Denver Mayor John Hickenlooper and Governor Bill Owens have proclaimed tomorrow ``orange Friday'' in Colorado. The leaders are urging Coloradans to wear orange in a show of support for the Denver Broncos. On Sunday the Broncos take on the Pittsburgh Steelers for the AFC Championship in Denver. The winner will go on to face either the Carolina Panthers or the Seattle Seahawks in Super Bowl 40.
