...tube is reflected by the blue-reflecting mirror, but passes through the red-reflecting mirror to the eye. Green light from the green tube is not reflected at all. It reaches the eye direct. The viewer sees the three pictures superimposed so that they blend to form a full-color picture...
Next step is to combine the three colored images in the eye of the viewer. The combining is done with two "dichroic mirrors": plates of glass with one surface covered with a thin layer of a colorless, transparent substance. Because of the special way in which this combination affects light of different wave lengths, each mirror reflects only one color. The other two colors pass right through...
...Color Now. To the FCCommissioners and other nonscientific listeners, the workings of the systems seemed far less complicated than the arguments about their comparative virtues. The solidest single fact is that the CBS system, developed to high perfection by Dr. Peter C. Goldmark, turns out pictures which are bright, crisp, and at least as faithful as most colored movies. Their own special ill is a so-called "color flash."

The colors are not at all faithful; they often change suddenly and erratically. Dr. Elmer W. Engstrom, research chief of RCA, admits that the system is still in the laboratory stage. But RCA-men add that the CBS color system has reached its limit: it has no "room for growth...
