The opening sequence of 'Seven' uses very dark and gloomy colours to set the scene, also the rain outside again signifies the gloomy theme of the film. The characters are also wearing really dark clothing to match the dark setting and theme.
The beginning of the opening sequence simply sets the scene and shows the audience what the film is going to be about and then the second half of the opening sequence is credits. The audience gather from the opening sequence that the film is about solving murders as we see a dead body and gather that Morgan Freeman is a detective.
The opening credits fit the theme of the film by being quite dark and scary. The music played throughout the opening credits is also scary and jumpy with high pitched sounds.
