Re: [neonixie-l] CRT colors

There are a variety of phosphors used in oscilloscope tubes. Here's a rundown: P1 is the original green. It's long lasting. P4 is white, faster. It's not common in smaller tubes, as it was used primarily for TV sets. P7 is a radar phosphor with a fast blue glow and a yellow afterglow. P11 is fast

Standard colo(u)rs I have seen are Green (P1, P31), white (P4), blue (P7, P11) and orange (P12, P19) https://en.m.wikipedia.org/wiki/Phosphor There are some exotics (like red) that allegedly exist, but I’ve never found a CRT with a red phosphor (yet...:). For a good vector graphics based CRT
