Another question?

Hi,

Me again, I was wondering if there was any substance that could exist in a gas state that would absorb light. Thanks for your time.

P.S. If not is there a substance like that, that could exist in any other state. If there is a substance like in my first question is it toxic to humans.

All gas absorbs light but it is usually in just one or two wavelengths IE. O3 or ozone absorbs uv whitch is just small light and ozone can even contribute to smog because it absorbs other forms of light. oxygen and nitrogen absorbe light too just not mutch. H2O (water) The No 1 greenhouse gass absorbs infraed but you cant see that.
