Here in the US there are two very easy methods that I use to color neon tubes. The first is Krylon "stained glass in a can". Available at craft stores such as Hobby Lobby. It's like regular Krylon except that the color is a transparent dye instead of a pigment. I use that for quickie jobs and jobs that aren't expected to have to last very long. For very durable coloring, and this should be available everywhere people build custom cars, I use the color coat of the candy apple car paint process. The stuff I use is a concentrated dye that comes in a pint can. It is added to the clear automotive paint system of your choice. For normal stuff I use ordinary acrylic enamel. Lacquer would be even more durable and shiny but it has to be polished, something practical for Nixies but not neon signs. For extraordinary stuff such as neon that goes on a tower sign, I use polyurethane epoxy paint (caution: VERY nasty stuff - supplied air respirator mandatory). This two part system is almost bullet-proof. In any case, I apply the dyed clear coat with an air brush. I like to use fairly thin paint and apply several coats. More uniform color than trying to do it with just one or two coats. Clear red neon sprayed with candy apple red makes a deep red that looks like you could swim into it. Even better color than classic colored glass.
