To celebrate its 50^th anniversary, the Hunt Library at Carnegie Mellon University received a makeover of sorts, with the purchase and installation of an exterior lighting system. The lighting, through the use of green technology in the form of color-changing LEDs, creates dynamic color combinations that bring the building to life. The aluminum and glass building was constructed through the generosity of Roy A. and Rachel McMasters Miller Hunt and was completed in 1961.  The Roy A. Hunt Foundation granted $200,000 to Carnegie Mellon University in 2010 to ensure that the unique features and building design of the library are visible at night through the use of different colors, lights and motions.
