Color tends to be a subconscious element in film. In what ways is color effective and symbolic in motion pictures? In movies like the Sixth Sense and Donnie Darko, color is a big element. As you watch the Sixth Sense you begin to notice the symbolic bright red little objects in many of the scenes. You do not realize until the end of the movie that the red objects symbolize death. In the movie Donnie Darko, Donnie begins seeing a human size bunny after he takes his medication. The color of the scene grows darker with just a small spotlight on the bunny. The bunny tries to make Donnie do bad things because it insists that the world is going to end within months. Color is a major factor in film. Color can create the whole mood of the scene or movie. When a director films a horror or sad movie, a lot of the color presented is dark and mysterious. When a director films a funny or romantic movie, the color of the scenes tend to be bright and happy. If the color in a movie is not set right, it could throw the whole movie off and make it an unsuccessful motion picture.
