Default N2 Gas to produce a color change



Is there any readily available household substance that will react with N2
gas to produce a color change ? or any other substance that reacts with N2
to produce a visible change ?

Oxygen

N2 + O2 -> 2 NO a toxic colorless gas
2 NO + O2 -> 2 NO2 a toxic brown gas
NO2 + H2O -> H2NO3 nitric acid, a caustic oxidizer, small amounts of
which can be detected with a pH indicator

The first reaction in the series only takes place at high
temperatures. Probably not a practical series of reactions for
demonstration or home detection system. What is your goal?
