re: Everyone knows why the sky is blue. Explain why clouds are white and
sunrise/sets are red.

Alternatively, why does the sky never appear yellow or green?  After
all, the sunset is red because of loss in energy of the photons.  Why do
they have to lose energy all the way to red - why aren't sunsets ever
green?
