I've noticed that Peter Pan has two different costumes. One is when he walks around the park signing autographs and posing for pictures. The other is in Fantasmic. In the costume where he greets guests as a normal character, his shirt is light green and his pants are dark green. In Fantasmic, its the opposite! His shirt is dark green and his pants are light green. Click on the links below to see the difference.

This is how Peter appears when he's walking around the park greeting guests.
