Yes I misstated. One of the constant complaints of the RCA system was the very dim color. One had to turn the lights down and draw the drapes in homes to see the image clearly. Another problem, color fringing on black and white programs and blurred images with color. This is why the Chromatron (and other systems such as the Apple tube by Philco) were proposed.

Chromatic Laboratory a subsidiary of Paramount Pictures Corporation built several prototype Chromatron chassis's which were encoded to accept one or three gun Chromatron tubes. Chromatic pitched the virtues of the design to all the manufactures. That is what I meant and should have said.

“Described in this paper is a single gun and three gun version of a simple color cathode-ray tube developed by Chromatic Television Laboratories, Inc., based on the ideas of Dr. Ernest O. Lawrence of the University of California. Both types utilize post deflection focusing (PDF) and acceleration as will be discussed in the body of this paper. The principles described are quite general and may be applied to other cathode-ray tube and camera tube designs. The single and three gun types discussed below will operate with any of the presently proposed color television transmission systems.”
