I don't know as I'd go that far, but it does require a basic understanding
of the theory.
One of the things I learned early on was that despite the density of skin
tone, the color itself never changed. Lots of folks will never believe
that, but its true, the vector angle of a skin tone remains within 2 or 3
degrees from the whitest Caucasian to the blackest African. The really
black black may not show as much amplitude, but if the camera isn't lying,
not by enough to be able to look at the scope and say that person is black.
We have had, for many years at my station, a pair of cousins who are color
blind, and did all their production work by checking it on the vectorscope.
It was right spot on moreso than the help that claimed good color vision.

That and the constellation. Without good performance there, you can't get
even a 100kw signal out of your shirt pocket.
