How did the first colored tv work mechanically?

The first ones used three picture tubes. Two to produce color images, and a third to help increase the contrast. But the key invention was an integrated circuit that could produce a full-color signal out of just three color elements. The picture was reproduced by controlling the intensity of the electron beams passing through the three electron guns, much like what would happen if someone were to paint a picture on three separate canvases.
