Talking of the Atari ST, there was an excellent example of this colour-switching in an ST software utility called Photochrome, which could use overscan effects, multiple palette switches per line, plus the colour switching technique in this article to greatly increase the number of perceived colours. It's the best example of this colour switching technique I've seen with barely any noticeable flicker (on a CRT-TV anyway). Seeing what was effectively a 'true colour' image coming from a machine that's only supposed to be capable of 16 indexed colours was a very impressive feat.
