--- Quote from: macboy on May 06, 2024, 11:14:00 pm ---I bought a pack of thin (maybe 0.8 to 1 mm) plastic sheets on Amazon, various colors. I think they called them acrylic but they were more flexible like polycarbonate. Used some for contrast filters on CRT oscilloscope, as well as VFD displays. My favorite color is "rose", kind of pale pink. It makes the VFD look white, by filtering out some blue and green. Can be combined with smoke for additional contrast. I've also used colored "gel" or cello or cellophane sheets, which are very thin. This needs to go in between the VFD glass and some other durable lens like acrylic.

Yeah, gel sheets are good, though you do need to combine them with a rigid sheet of something. They are available in a large range of colours too
