http://en.wikipedia.org/wiki/Technicolor
Two-strip Technicolor was available in the silent film era (1922), but
in a process where two separate pieces of film were cemented together
to make a projection print. The next generation of two-strip
Technicolor (1928) eliminated the cementing.
The lens image was split into two and exposed onto two separate pieces
of black-and-white film through green and red filters. The resulting
images were then alternated and printed onto film stock where the
color gels were also alternated.
Even the earliest of these films used a synchronized soundtrack, for
music and sound effects, or for part-talkies where some of the film
was color and some black-and-white.
According to the Wikipedia article, this process was improved in 1931.
