L.A. was notorious for its smog in the '70s.
Could it be because of low quality film stock? I don’t know about TV, but a lot of movies in the 70s used Eastmancolor, which was pretty cheap and nasty, and made everything look brown, grainy and washed out.
The color errors with NTSC occurred during the transmission, so this would not have any effect on the source material.
I grew up in the 1970s in the United States. Where I grew up, it was possible to receive several Canadian television stations. While I also remember colors from American television programming of the era being muted and brown, Canadian programming was even more muted. Even today, when I flip back and forth between the same show on an American and Canadian station, the Canadian station will display more muted colors.
Game and variety shows from the 1970s definitely had more vivid color than prime-time programming, news, and daytime programming.
I don’t think it was the televisions of the era. Ever see the display on a 30 year old television on cable or with a DTV converter? If the TV isn’t broken, the display can be quite sharp and vivid. The RCA CT-100, the first commercially sold color television, was known for having one of the most accurate CRTs ever, with a much wider color gamut than CRTs that followed.
I wonder if that is where the Simpsons got their coloring.
Nah, he is actually an Oompa Loompa.
The original post references One Day at a Time which was taped, not filmed.
