There's clearly redshift a ways out from the horizon. I believe what you see 
between the red ring and the horizon is light that has been "slingshotted" 
around the hole - that is, you're seeing stars from behind your back. That 
light would blue-shift going in, and red-shift coming out again, to balance 
out.
