The standard NTSC red primary is a bit orangy - for example, traffic signal red is outside the gamut of NTSC.
The original red phosphors were close to NTSC standard. The all-sulphide tube (zinc cadmium-sulfide for red) was probably the most orange, and got worse at high beam currents. The vanadate rare-earth red was pretty close to standard. The europium red that eventually became the norm is a bit orangy again, but not as bad as the sulfide.
Vanadium and europium are "rare earth" elements.
