Black and white is an art form in and of itself. Sometimes it lends a creepiness factor (intended or not) that just isn’t there in color. The Twilight Zone seems like it was made for black and white. I’m not sure how a color Twilight Zone would work (I know remakes exist, I’ve just never seen them, and am not so sure I’d want to).
Similarly, I just cannot get my head around a color Andy Griffith Show. It just seems wrong somehow. (But I did like the episode where Howard Sprague goes to live on the Caribbean island of “St Benedict”.)
And you can always make a color movie or TV show black and white — just turn down the color to zero. I guess TV sets still allow you to do that. (I explain to my son, who just turned 12, that we did not have a color TV set until I was 10, and when I was about his age, our town got cable, which furnished us with 7 channels instead of 4. He thinks that’s pretty gross.)
