why are they wearing white on gameday

They are wearing white on gameday to participate in and honor Penn State's annual "White Out" tradition. This tradition, started in 2004, involves fans at Penn State's Beaver Stadium dressing entirely in white to create an intimidating and electric atmosphere for the home football game. The ESPN College GameDay crew also wears white suits to visually blend with this all- white crowd and pay respect to the tradition during the live broadcast. The White Out is known for its loud, intense atmosphere and is considered one of college football's most iconic fan experiences.
