The opening sequence of Dawn of the Dead uses quick flashing images of vicious zombies with blood around their mouths to establish them as the cause of widespread disasters like fires and ambulance sirens. Questions are asked about whether the affected people are alive or dead and if it's a virus, showing a molecule to confirm it's a contagious disease. Shaky camera footage gives the scenes a sense of being actual news coverage from the event. Red and black colors are used symbolically to represent blood, death, and evil relating to the zombie storyline.
