The day is often associated with orange and black, and is strongly associated with symbols like the jack-o'-lantern. Halloween activities include trick-or-treating, wearing costumes and attending costume parties, ghost tours, bonfires, visiting haunted attractions, pranks, reading scary stories, and watching horror films.
Trick-or-treating is a customary celebration for children on Halloween. Children go in costume from house to house, asking for treats such as candy or sometimes money, with the question, "Trick or treat?" The word "trick" refers to a (mostly idle) threat to perform mischief on the homeowners or their property if no treat is given. In some parts of Ireland and Scotland children still go guising. In this custom the child performs some sort of show, i.e. sings a song or tells a ghost story, in order to earn their treats. - Wikipedia.
