I recall as a kid seeing a couple of pseudo-color display gadgets in department stores, in the early 1960s.
One was indeed a spinning disc that stood in front of the set, made up of segments of variously coloured celluloid or a similar material. The effect was rather underwhelming. A character on screen would be alternately red, green, blue, yellow, red, green, blue, yellow... "color TV" in a very strict sense of the term indeed.
Another device was what in hindsight I suppose was some sort of polarizing filter that fit over the screen. Viewed at the right angle it did tend to impart an orangey tint to skin tones, making it at least quasi-realistic. I never saw either of these items in stores more than a couple of times, so I suppose they weren't runaway hits.
The first color TV owned by my parents was a Heathkit built in 1966 by my grandfather, an electronics engineer and hobbyist. In his retirement he also bought one of the original TRS-80s to tinker with.
