Definitely not a sulfide red, which was the most orange of any of the reds used over the years and moved significantly more toward orange at high beam currents. The rare-earth red is actually quite close to NTSC red, and mainly appears wrong in later sets due to the large color demod/matrix adjustment needed to compensate for the yellower sulfide green phosphor.
