That’s right, “The Matrix” was released in 1999, in the pre-digital color grading era. Actually, just one year before as, if I remember correctly, “O’Brother, Where Art Thou?” (2000) was the first movie to be digitally color graded. Now, the two sequels were color graded in the digital era, and then, the Wachowskis went back to color grading the first movie to match its sequels. The second film scan, from which we can see some pictures above, is probably from a rerelease for trilogy marathons. During production of “The Matrix”, the way the green was introduced in the Matrix scenes was done on set: lighting, set designs, green paint on the walls, green fruits on the street market, etc. Even if the Wachowskis had this idea from de beginning, they just couldn’t do it the way they wanted in the pre-digital era.
