Ooops. The Apollo color cameras were also field sequential color cameras. They just had one single tube and a color wheel in front with three color filters. The camera transmitted sequentially filtered images which were again combined into color ones on earth.

Not the best example for your case ;-)

PS: The ALSJ is currently collecting up lots of old documentation on the Apollo cameras. Have a look at http://www.hq.nasa.gov/alsj/alsj-TVdocs.html
