Film posters use various codes and conventions to advertise films and provide insight into their narrative and genre. Typography on posters corresponds to the film's genre to make it more eye-catching. Photographs and illustrations also correspond to the narrative and genre, showing characters, actions, and plots. Lighting sets the mood, with dim lighting for dark films and bright lighting for happy films. Color schemes are used cleverly, with colors like red connoting love in romances but danger in horrors.
