I'm sure you're seen either The Wizard Of Oz, or even some of those really old school Loony Tunes cartoons for the 40's both are examples of 3-Strip Technicolor. Good examples of 2-Strip Technicolor, I can think of off the top of my head, are Doctor X (1932), Mystery Of The Wax Museum(1933) and the color segment in Phantom Of the Opera(1925). Yeah, I'm not really old, I've just watched way too many movies made way before I was born(1982).
