Color crt question???

This reply received from Chuck Prazak, former VP Engineering at Rauland:

Yes. The cadmium sulfide red phosphor was a strong, deep yellow color. The zinc-cadmium green was light yellow and the zinc sulfide blue was white.
Even after the rare earth red was introduced, the screen color was still slightly yellowish due to the color of the green phosphor.

I think that's definitive! The olive-green appearance would be the combination of the phosphor colors and the dark (neutral) faceplate tint.
