Neon does in fact emit at least one green line, at 540.1nm. There may
be others but that's the one I recall offhand. As I mentioned they are
very dim compared to the red and orange lines. You should be able to
see that line in the output from an NE2 if you look very carefully.

Neon itself
has several green spectral emission lines, hence the
existence of "GreNe" lasers, but they are of far lower in intensity than
the red/orange lines.
Every green gas-discharge bulb I've seen has had a phosphor coating
somewhere, so my assumption (and that's all this is) is that there's not
enough intensity there to be useful.
Last time I looked at neon spectrum from a NE2,
There were no green lines. There was a yellow and
as I recall 2 reds but no green.
I don't know how a GreNe works but it isn't a normal
discharge color.
