Is there a model line of CRT tube that's available in different colors?
Alternatively; know of any analogue oscilloscopes that came in different
colors?
many of the makers did offer other phosphors in 'scope Tubes. BUT
normaly the effort was to control the persistence of the glow. Take the
P7 used fro Radar displays for example. a very short blue-ultraviolet
display, followed by a 2 second or more yellow glow. there was an
Orange long phosphor also in some lines.
Sylvania even made some tubes with a two colour phosphor - which one
glowed depended on a drive signal.
this link has scans of some of the standard versions from different firms.
