RCA published a paper showing that the color errors were not too bad, but nevertheless, the tendency would be to lighten saturated reds and blues on a normal NTSC receiver. This could be compensated somewhat by deliberately pulling the blacks lower in the luminance tube channel I suppose (or by modifying the luma tube optics to favor green), but the three tube camera by comparison could have more accurate color.

Thanks for the added illuminating information.
