Sixth Sense, The Easter Egg - The Color Red

Throughout the movie, whenever a dead person is in the room or about to appear on the screen, someone is wearing red. For example, Cole's bright red tent. Whenever he is in or around it a ghost appears. It makes more sense if you watch the whole movie and watch it again with the ending in mind. Its fun to look for,and tells you when a ghost is near. Happy Hunting!
