Color Existed Before 1935

As far as I can tell this shot of Joan Blondell, taken sometime in the early ’30s, is colorized. It seems that almost no color shots of movie stars were taken around this time, and certainly none in the ’20s. Perusing top-quality color snaps of the big stars of this era would be fascinating. But there are none of these apparently, and so these people seem to exist only in a silvery black-and-white cocoon. If anybody knows something I don’t, please advise.
