The iconic Tower is The University of Texas at Austin’s most recognizable landmark, and 2015 brought plenty of reasons for the Tower to show off Longhorn pride with a burnt-orange glow.

The standard all-white configuration illuminates the Tower in Austin’s skyline most nights, and a handful of other lighting configurations convey signals of celebration, accomplishment or, sometimes, sorrow.

From the orange top best known for celebrating football victories to the windows lit in different formations bidding farewell to a graduating class and welcoming incoming freshmen, the Tower had special lighting configurations more than 30 times in 2015.
