I went to Universal for the first time about a month ago....and I went and paid a visit to the former mecca for kids in the 1990s- Nickelodeon Studios, which is now the Sharp Aquos Theatre that hosts Blue Man Group shows. However, I found this on one of the doors in the front of the main building:

Pretty neat, huh?
The railing on top is also Orange....and you wouldn't know it, but they still have lots of Nickelodeon stuff still up on the 2nd floor, I think.
