If the sky is blue because of the polution and stuff, then why is the sky
bluer where there is less pollution? Perhaps a science teacher could answer
this question. Just why is the sky BLUE?
On the days when pollution is high, the sky gets gray...on the days when the
Tramontana wind is blowing all the pollution away, the sky is a bright blue.
I will never forget the African sky where there is little pollution and
what an incredible clear blue it was! Also if you are painting a
landscape, the trees that are bright green in the foreground are much bluer
in the distance....so the air between you and the distance trees affects the
color. Mountains in the distance are blue even if you know they are covered
with green trees.
So what makes the sky BLUE? Excuse my ignorance.
