Blue and White
The University of Kentucky adopted blue and white as its official colors in 1892. Originally, however, UK students had decided on blue and light yellow prior to the Kentucky-Centre College football game on December 19, 1891.
The shade of blue, which is close to a royal blue, was chosen when a student asked the question, "What color blue?" At the time, Richard C. Stoll (who lettered in football at UK in 1889-94) pulled off his necktie and held it up. The students then adopted that particular shade of blue.
A year later, UK students officially dropped the light yellow color for white.
