Gotta be careful with how you tune the towers...

Measurements from NASA’s Lunar Atmosphere and Dust Environment Explorer, aka LADEE (pronounced “laddie”) have confirmed the long-suspected presence of neon in its atmosphere ... along with isotopes of argon and helium. The relative concentrations of each of these elements also appears to depend on the time of day.
“The presence of neon in the exosphere of the moon has been a subject of speculation since the Apollo missions, but no credible detections were made,” said Mehdi Benna of NASA’s Goddard Space Flight Center in Greenbelt, Md., and the University of Maryland, Baltimore County, lead author of a paper describing the findings. “We were very pleased to not only finally confirm its presence, but to show that it is relatively abundant.”
Of course, this has nothing to do with the appearance of the moon from Earth. Despite its “relative abundance” the amount of neon in the lunar atmosphere is much too sparse to actually create any visible glow.
These elements in the lunar atmosphere have their source in the solar wind. As this constant stream of charged particles from the sun encounters the moon, heavier elements remain on the surface while lighter and more volatile elements like neon and argon return to space… except for the small portion that get trapped by gravity.
While we say “atmosphere,” in realty what the moon has is an exosphere — an extremely diffuse cloud of atoms, ions, and fine dust particles held in place by the moon’s weak gravity. It’s nothing a human could breathe or even feel; it’s 100 trillion times less dense than air on Earth at sea level.
Still, it’s something that interacts with the solar wind environment and, possibly, whatever activities we may one day establish on the lunar surface.

Laddie eh? Well, get yer arse home right now, ye wee bugger!
Not all that impressive to anyone who’s seen Tokyo’s Ginza at night.
