Ucc is a common term for supply voltage
Yes, a very low pressure and a low voltage make digits very fuzzy. See

Anyone have a favorite microprocessor for driving the 24 74141 inputs on this
sucker?I'm considering taking advantage of this project to do my first
tutorial on shift registers using the 74HC595 with an Arduino, but am not
opposed to directly controlling them all individually with a IC
Thanks Dave,
;-)
No problem, I'm far above any childish comments. I forgot the U is not so
well known at Neonixie.
U = the formula symbol according to DIN 1304 for the Voltage.

I only know that U means voltage because I work on a fine German telescope.

Ucc = Ukk = Voc = Uclamp = cold cathode voltage = off cathode voltage (kk =
kalte kathode (German)).
I had remembered that U was used for voltage in Europe (and B in Russia), but I
was a little confused by cold cathode, as all nixie cathodes are cold. I had
surmised that it was off cathode,
The voltage measured from GND to the switched off cathodes.
At dircet drive, the Ukk is equal to Ua (Ua = Va = Up = Vp = Anode voltage
= Supply voltage = Plate voltage)
Not necessarily - if you're direct driving them with 74141 chips, Ucc
would be about 60 volts, and with K155ID1 chips, about

The purple, pinkish or peachy haze comes from the different additional gases
and the mercury inside the tube.
You may find out from the spectrum (in some cases) what mixture is in the
tube.
Second, the lower the Ucc (cold cathode voltage) the higher the haze. And
the more blurred the glow.
