Whatever angle the TV camera was at was an impressive array of that yellow/gold, whatever color it is.
Even my wife commented on it, so I know I wasn't hallucinating.
Edit: It could have been their student section. The SWARM is the only section of our stadium that is uniform gold. The frats, when they don't show up late and leave early, are not color coordinated. The band of course is pure white. Also, the "other student section" on the south side (other than the front row Goldfellas) is never uniform in color.
When I say uniform, I mean like >90%. You can clearly tell that not enough people know to wear gold.
Edit 2: I just wish we could pull off something like Penn State. I remember one of their games where the entire stadium was white. And the students had the free pom-pom things moving in a coordinated fasion. It was VERY impressive.
