That color is looking real good! I keep having to tell myself the colors are not wrong since most of the color bars look different than what I am used to on regular sets. But just about every photo I have seen of 15GP22 color bars look the same, with the deeper green and somewhat muted yellow. These must be the intended NTSC colors in this case.

Yes, 15GP22 green is P1, less yellowish and darker than later tubes. It really is 59% of the white brightness as spec'd by NTSC.
