All electronic signs are called "neon" light but different gases in the disharge tube, where a low pressure gas is exposed to a high voltage, will produce different colors dependent on the nature/type of gas and whether mercury vapor is also present as well as the nature of the glass.
Krypton can form white/yellowy lights.

Krypton was discovered spectroscopically, where light is split into characteriastic wavelengths. Here Chemistry One students are studying the spectra of lights and elements.
