One odd variation was that the 21CT55 demodulated along R-Y (wideband) and Q (narrow-band) color axes. I once was able to interview Dalton Prichard, the Guru of color receiver design at RCA Laboratories in Princeton. Dalton recalled that there was some patent dispute associated with the continued use of "I,Q" color demodulation, and that "one resistor was saved" in the matrix section of the 21CT55.
