The title of the film 'Friday The 13th' is written in red. This connotes blood and gore. Also as the background is black the red title stands out and is eye catching to the audience.
From this poster we can also see that the villain is standing in dark woods. This suggests to the audience that the setting for the film is based here. This may make them more interested in the film because most successful horror films are located in the woods or other isolated locations like this to create a scarier atmosphere. This is due to the fact that the victims will be alone.
