Lunar eclipses, viewed from the moon
What would a lunar eclipse look like viewed from the moon?
When the moon moves into the Earth's shadow, I've seen it go through a number of colour changes before settling on a deep red for the duration of the eclipse. My assumption is that there is still light reaching the moon, being refracted via the Earth's atmosphere. So to an observer on the mooon, would they see a rainbow halo around the Earth, followed by a red ring?
Has it ever been observed?

A 'lunar eclipse' (from an earthly point of view) would be a 'Solar Eclipse' wheb viewed from the moon. Since the corona visible from eart during a (terrestrial) solar eclipse results from the fact that the apparent size of the moon and sun from earth are almost exactly equal, and considering the relative sizes of earth and moon, it seems very unlikely that any similar corona or 'halo' effect would be visible from the moon.
It would be very interesting to know whether there are any pkotos (eg from the space station or a shuttle) that would confirm this.

You have the clues necessary in the original question. The moon surface appears dull red, so an observer on the moon will be seeing red.
When the earth obscures the sun (seen from the moon), the sunlight is not totally cut off because the earth has an atmosphere. This refracts light around the rim of the planet and would appear as a continuous sunset around the whole rim just like a red afterglow once the sun has set on earth.
