Many good points. I'd add:

than we are usually aware of

This is far more true than folks admit to, Tomas. Back when US TV was
broadcast in NTSC, the people in the
ditch, aka the switchers in our parlance, in charge of the switching
between programs and commercials, were
often varying degrees of color blind. I've spent nearly 50 years keeping
one tv station or another on the air
so I've had a long tine to observe broadcasting from the station viewpoint.
The best of them learned to read a "vectorscope", and the more color
blind they were, the better they were
about twiddling the dial to get the correct color. The vectorscope did
not lie. Something I always had to
teach new hires about.
Something else I should mention, is that the vectorscope itself was
color blind in that on the scope, a black
persons face was exactly the same color, the melatonin in their skin was
just a lower brightness version of
the same color. The actual vector did not change.
Take care & stay well, Tomas.
Cheers, Gene Heskett.
