There are a lot of videos of early color broadcasts from the 1960s on Youtube.
Here is one .. the 1966 US Masters Golf.... apparently the first broadcast in color?
In fact the very first program I saw broadcast in colour was golf in October 1974 during colour broadcast tests here in Australia.
Even now I remember the shock of green ....
