i was thinking maybe a chemical that is cheap to produce, like for use in a sales product. I read up on Leucomethylene blue and it is used to lower the levels of methaemoglobin in red blood cells, sounds kinda expensive.

Is there a chemical that is non-toxic, clear, and goes from clear to a color when it comes into contact with oxygen or carbon dioxide? kind of like how blood turns red when it comes into contact with oxygen.
