I think  a good approaach to understand those greenish displays is: 1)
tweaking pots and trackballs watching the results first- on the waveform and
vectorscope and then seeing the results on the master monitor.  2) Same
tweaking -trusting on your eyes looking at "the glass" and then see the
results onto the greenish guys.  3) Talk to the engineer of the house to
lear the theory...  4) Think the waveform represents a lansdcape -whites on
the top and blacks on the bottom. Is not so simple, isnt it?  5) Think the
vectorscope is like a cone looked from the top.  The center is the absence
of color.  The extremes are the opposite.  Lot of chroma.  The bottom center
is the black.  The top center is the white.  6) Looking at the circle of a
vectorscope -clockwise- shows transitions -many differents ones-:)  the
colour of the four seasons of the year; the colours of the wines; the colour
of the hours of a day; the colours of the ages of a human being.

I am not Jais Lamaire gentlemen.  Do not misunderstood, please.

PD:  Those books are great.
