Cleaner Air

[oneshot]

Ok we live by Bennett Spring. Not where air is polluted.

But look out my window the sky is a light Blue.

In the mountains the sky was a dark Blue.

Is it just cleaner air in the mountains?

No. The sky and air are colorless gases. The color you think you see is caused by light absorption and scattering. Blue light is the least absorbed by the air.

When the air is dirty you will hawk up and spit black mucus and blow black snot from your nose, I went to Basic in San Diego and every morning about 8:30-9:30 the air would become dirty with smog from LA. Makes my nose itchy just thinking about it.
