Duke blue
Duke blue is a dark blue color used in association with Duke University.
History
The origins of Duke blue lie in the uniforms worn by the Duke football team in their first game against the University of North Carolina in 1888. These were a grayish dark blue, chosen by the team as an approximation of Yale blue to honor the college's president, John Franklin Crowell, a graduate of Yale who had introduced football at Trinity.In 1961, Duke University President J. Deryl Hart recommended a standardization of the shades of blue used by the university when it was redesigning its academic gowns. In 1965, Duke's board of trustees officially adopted Prussian blue for official university use.
