The black and white cameras I mentioned earlier were the industry-wide standard, as were the color cams a few years later. They were not exclusively used for video recording, however. They were often used for direct broadcast transmission (live TV). I believe that kinescopes from many live shows were filmed directly from the camera monitors located on the CCU's(camera control unit). As we know from DS, even color broadcasts were often kinescoped in 16mm black and white film.
By the way, the comment about white balance and camera color output makes total sense. I have had experiences with more modern Vidcams where my image would "blue out" if I had foolishly neglected to white balance the image before active taping. I'm sure that even a seasoned professional could occasionally make the same mistake, particularly under the daily pressure of soap opera production.
