Therefore ever since Blu-ray came out they have tended to try to fix the problem of the past on a format where it isn't really a factor anymore, by turning down the red and turning up the cyan.
Oh well, hopefully next time they'll get it right or a least closer to what it should be.
Actually, ever since Blu-ray came out, most films have been pushed to be restored by people that care, which includes proper color timing.
Why the cyan thing has become popular doesn't really have anything specifically to do with home video. It's fad in Hollywood, blockbusters in theaters right now have it. It has to do with skin tones and complementary colors.
I posted this link on page 1, but I guess you missed it:
Apparently just about everyone in Hollywood is now drinking the teal/orange Kool Aide.
Because of this they are retroactively applying it to some re-releases of movies (for example: James Cameron signed off on doing it to Aliens when it was released on Blu-ray), while really most are treated with respect and restored properly.
