Let's not forget that tube gear (cameras and receivers) was a lot less stable than transistorized sets, and the variations from set to set and program to program were pretty huge. The question repeatedly asked was "when do you think they'll perfect color TV?" When I was a kid, I just ignored it, but when I became an engineer, I always answered "I hope they never do - that's my job!"
But really, some of the things done to get brighter pictures (new phosphors) and brighter-looking pictures (9300K bluish "white" ) made it even harder to get consistent flesh tones, and I remember often seeing blond hair that would look unaturally greenish, for example.
