Diopter -6.75 here, though at the moment I'm wearing contact lenses at 
-6.50 so I can't see the effect.  The black you're seeing is the non-blue
components of the blue hexagon, overlapping the non-red components of the
red hexagon.  If your hexagons were yellow and cyan you might actually
see green in the middle (I think... as I said, I can't see the effect
anymore since I've started wearing contact lenses.)  The effect is 
even more pronounced if you wear polycarbonate or other high-IOR lenses.
