what is neon atmospheric landable?

I am scanning an undiscovered (Until just now) system that has neon atmospheric landable planets and moons and I do not know what that means. Are they lit up in neon colors LOL?
A google search gave me nothing.

Thank you.
 
Neon is a noble gas like argon and Helium. It can make bright colors
