Well, for anyone who ever watched TV in the 70s and 80s, that's the way almost every show looked on the air in syndication. 16mm prints, whose color faded over time. It was only starting around the mid-80s that syndicators began going back to the original elements and remastering and color correcting shows. That is, syndicators that cared about their back catalogue. Fox was really the only company that didn't do it. Which shows that they sucked even back then. But it had to be shows that the syndicators deemed to have some kind of sale value and unfortunately, not too many Fox shows besides Batman fall into that category.
