Radon is a colorless gas.
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.
In its gaseous state it is colorless, but when it freezes at -71°C the cooled, solid radon emits a pale yellow light. On intense cooling, it glowswith a orangish color.
The color of the tube for electrolyte testing is typically green.
The B12 lab tube color is typically red or gold.
The color tube for bilirubin direct is usually a green or dark green tube.
None of the noble gases, such as helium, neon, argon, krypton, xenon, and radon, are orange in color. Orange color in gases can be produced by other elements or compounds, such as nitrogen dioxide or mercury vapor.
