Yes once with an eclipse many years ago I had some really good night time binoculars and I wathed it change to a very blood red color as the eclipse took Place it was an extrordinary site. I had sat a chair up in the bed of the pickup and sat for a very long time outside that night watching the whole process.. It was not that long a period but it was truly beautiful! It was when Sarah was little so between 1981 and 84 as I can't remember the year!

The reason the moon changes colour in an eclipse is that the only light that can get to it is refracted through the atmosphere because it is in the earth's shadow, so it actually goes red.

I wrote an article on this a while ago:

I think it is also possible to get a slightly coloured moon when it is rising or setting for the same reason that the sun goes red at sunrise or sunset:

There are lots of tiny particles in the atmosphere that will tend to scatter blue light more than red, so the red light carries on straight to you and the blue tends to go somewhere else, hence it looks redder. At sunrise or sunset the light has to go through more atmosphere so it looks redder.
