The theme of Halloween is ghosts, scary, and things related to death, magic, and monsters.

Black and orange are the traditional colors of Halloween. Modern Halloween products also use purple, green and red in large quantities.

Autumn elements such as pumpkins and scarecrows have also become symbols of Halloween. Commonly associated with Halloween are pumpkins, ghosts, ghouls, witches, bats, black cats, owls, elves, zombies, beggars and demons, as well as fictional characters such as vampires and Frankenstein. In addition, the Jack Light is the most widely known symbol of Halloween. In the UK and Ireland, the locals originally lit candles in the hollowed out of the turnips to create Jack lights, but those who immigrated to the United States quickly replaced them with pumpkins because the pumpkins were larger and easier to engrave on them. Many families engraved a scary face on the pumpkin and placed it on the ladder at the gate. Traditionally, this was to scare away demons or monsters.
