Purple CRT?

[wa2ise]

Maybe that set with the purple screen has a replacement green phosper CRT and has a purple colored filter in front to make it look less green (at the expense of brightness)?

Back in the 80's, GE had sets with CRTs that would look to be dark blue when the sets were turned off.

I believe that those CRTs have the standard white phosphor but have a purple filter in front. Sort of like the Hoffman Easy Vision idea.

Steve is correct. I own a PYE LV30 with such a purple filter in front:

The CRT is a common MW22-17 (with an ion burn in the middle of the screen). This purple filter was used to suppress reflections on the screen and to generate more contrast.
