   If you were on the Moon during totality, you'd see Earth not as a black   
   disk, but as a black disk with a red ring around it.  Some sunlight,   
   mostly the longer (redder) wavelengths, reaches the Moon by scattering in   
   the atmosphere around the rim of Earth.  So the Moon is still faintly   
   illuminated with reddish light even during total eclipse.
