I know my father used to talk about some type of technique that was experimented with by advertising companies shortly before color TV came out which did some sort of flashing or such in front of the picture to get color (perhaps this spinning disk?). The reason he always remembered it was because it had an interesting side effect, in that one of the observers was color blind, and he was able to see colors for the first time with this technique!
Unfortunately, I don't know more about this, as he was not a technical person, and is no longer around to ask for details.
