The base of the stadium's facade is clad in limestone-like stonework while the rest of the stadium is distinguished by an outer skin of aluminum louvers and glass and by interior lighting capable of switching colors, depending on which team is currently playing–blue for the Giants and green for the Jets. This idea originated at the Allianz Arena in Munich, Germany; which was previously shared between the city's two major soccer clubs, Bayern Munich and 1860 Munich. Unlike Giants Stadium, MetLife Stadium can easily be reconfigured for the Giants or Jets within a matter of hours. The louvers' total linear length is exactly 50,000 meters (50 kilometers) or 163,681 feet (31.1 miles).
