The second type are clear, because they're just glass tubes with

That's interesting, because at Magna we had bottles of Argon as used by
signage designers, mounted in a case, with 22kV (or something) clunked
onto each end when people walked past.

The "sparks" inside were definitely mauvey - I'd say more towards the
