Thanks for the link. It was very enlightening. Apparently, the process was also used employing a special film in the late 1950's called the "Nagler Process." Makes me wonder if a true white LED could be manipulated to produce the illusion of different colors. Imagine a matrix of LEDs creating images or messages that would be visible only to a certain percentage of viewers. Everyone else would only see white. I'll bet some people could be convinced that they were being hailed by God.
I fully appreciate the last bit in the article pointing out that thousands of viewers telephoned a station asking, "What happened? Did I really see color on my black-and-white receiver? Or am I having hallucinations?"
That's exactly how I remember feeling.
