What is the color of radon?

In the gaseous (normal) state, radon is a colorless gas, as is true of all noble gases (see: xenon, krypton, neon, argon, helium). Due to its high radioactivity a radon light is impractical, but if one were constructed it would glow yellow-green. In the solid state, things get very interesting with radon. As radon solidifies, it glows yellow, and then with decreasing temperature, glows an angry orange-red. This glow, or nightshine, comes from the Cerenkov light -- a product if radon's intense radioactivity. Needless to say, if you ever are viewing a glowing radon tube, you had best be standing behind very thick leaded glass.
