I was pondering this - must have to do with particle size. Typical atmospheric scattering happens off molecules and is called Rayleigh scattering. It strongly biases scatterability toward the blue end of the spectrum. Thus the sky is blue with scattered light. The red sun is unscattered, and it went thru a lot of air so the blue end got pretty much all scattered away. So the red clouds are lit up by a red sun punching thru several hundred miles of atmosphere. Dust and cloud work differently. Bigger particles; different scaling law. When the sun is half-hidden by cloud where you can look straight at the disk - it has a slight blue-gray cast.

OK, I was feeling guilty about posting the "Useless Factoid" site, because I so much enjoyed your post about the music timeline, and was afraid that I had distracted you from explaining about the avocado tree and Sting Rays, and all. So, to make amends, here is something worthwhile. Unfortunately, it won't keep you from being too distracted to explain about the avocado tree, nor will it keep you from riffing on the music timeline, but, but, but - - I trust you will come back to us with fresh insights, anyway: howstuffworks.com
