The Matrix, Behind The Scenes

• Production design
In the film, the code that comprises the Matrix itself is frequently represented as downward-flowing green characters. This code includes mirror images of half-width kana characters and Western Latin letters and numerals. Generally, the film's production design placed a bias towards its distinctive green color for scenes set within the Matrix, whereas there is an emphasis on the color blue during the scenes set in the real world. In addition, grid-patterns were incorporated into the sets for scenes inside the Matrix, intended to convey the cold, logical and artificial nature of that environment.
The "digital rain" is strongly reminiscent of similar computer code in the film Ghost in the Shell, an acknowledged influence on the Matrix series . The color green reflects the green tint commonly used on early monochrome computer monitors.
