Indeed, Sir

1929 (more or less) is the date of the commercial application of the three-color movie film process. (It existed earlier - but was not in commercial use due to various problems in process.) This - and the majority of other early color films - show the results of a two-color process. (Note the strong blues and reds, the almost absent greens, and the totally lacking strong yellows?) earlier 'color' films used a one-color process (changing sometimes by scene) with hand tinting on the film print itself to expand the color range.

Now - as to our corner of the fix-dom?
Bertie would love color films.
Jeeves would prob. consider them vulgar.
