Resident Evil almost shipped with a very different splash of horror in Japan. Former Sony Computer Entertainment executive Shuhei Yoshida says Sony asked Capcom to test green blood for the original PlayStation game before its 1996 launch, out of concern that red blood could be too disturbing for younger buyers.
The detail comes from a short video message celebrating Resident Evil's 30th anniversary. According to a summary shared by series researcher Alex Aniel, Yoshida said Japan did not yet have a standard games age-rating system at the time, and Sony wanted PlayStation to feel broadly accessible.
Capcom tried the change, but the experiment apparently hurt the game more than it softened it. After seeing Resident Evil with green blood, the team decided it "didn't have the right atmosphere," so Sony agreed to keep the blood red.
Instead, Capcom added a warning to the Japanese box telling buyers that the game contained violence and gore. That small packaging solution preserved one of Resident Evil's defining visual details at a point when the series was still a new PlayStation risk, not yet Capcom's long-running survival horror pillar.
The Western releases followed a different ratings and censorship path. Resident Evil was among the earlier games to receive a Mature rating from the ESRB in North America, while the UK release carried a 15 rating. Its Western intro sequence was also censored, trimming some of the gorier material from the live-action opening.
