The origins of Duke blue lie in the uniforms worn by the Duke (then Trinity College) 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.[3]

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.[3]

Modern usageEdit

Duke makes use of several shades of blue, with the official Duke blue, known as Duke Navy Blue, being the darkest of the official blues.[1] The dark blue is used on the official university seal, but a lighter shade of blue, known as Duke Royal Blue (Hex: #00539B), is used on the Iron Duke logo, the logo of Duke Athletics.[1]
