This nine set of lunar eclipse images shows you the change of color of eclipsed shadow by exposing long time. Although the color looks indistinct in the first half of partial eclipse due to the thin clouds, I could appreciate beautiful bloody-red full Moon during totality. You can see that the edge of Earth shadow has a bit bluish color.
  All images are displayed turning the celestial north direction upward.
