I'm a little confused as to your wording of this question. An oxidizing agent, by definition, is a molecule that readily transfers oxygen atoms. So exposing it to oxygen wouldn't cause any color changes, because oxygen is already present.

Vicinal dibromides, when dehalogenated, give off Br₂, which is a brown liquid at room temperature. Dehalogenation is a reduction reaction though.

I'm probably missing something obvious here. As it is though, I have no clue.

Im sorry,
Im not very good at chemistry I just do it for fun haha
I was told it was a chemical that when disolved in alcohol
it is clear but when aplied to a surface it turns a brownish color after about an hour

like when you eat an apple it turns brownish
look up stealth ink on youtube
I dont really approve what they are doing it for but its very clever
