A Youtuber called Generation Gap Gaming posted a pretty compelling theory as to why the old 1989 Friday the 13th game for NES featured a strangely purple and blue Jason.
Though every fan of the game knows it was published by the infamous LJN, makers of bush league, cash-grab games based on movie titles, it was evidently created in 1988 by a Japanese company called Atlus. While the programmers were looking for inspiration, they evidently found the back cover of an older promotional book for Friday the 13th Part 3's Japanese release, which featured this fanciful image of purple and blue Jason:
Why they took such liberties with the program cover is unclear. But this seems like a pretty good explanation for why a Japanese company made such a strange edit to Jason's palette.
