A colorblind firefighter saw the American flag in all its red-white-and-blue glory for the first time in 21 years after his friend and colleague surprised him with a pair of special glasses that allowed him to see color. Firefighter Spencer Caradine, 21, of Dallas, couldn't help but burst into tears. "I was overwhelmed," Caradine told InsideEdition.com. "I didn't know what to think or say. It was like entering into a whole new world. I didn't know how to explain any of it."
