I know one early pilot was, but it seems to me that color became viable widespread for tv at just the right time for TOS. My question is how would it have done in black & white? Color seems RATHER important in the show, Red shirts, rank depiction etc.
As late as 1965, CBS provided only 800 hours of color programming the entire year and ABC only 600 hours. As of 1965, only 10% of U.S. homes had a color set. It was not until the late 1960s, over a decade after the standard was set, that color TV sales rose significantly.
