Interesting to read this article on different monitors to see the colors be rendered so the greens and the blues can be barely told apart on the one monitor and are clearly different on another. I wonder if that was taken into account during the study but it would seem to me to be pretty important since 'red' appears to be rendering mostly correct on all of them.
That really depends on what you think of as "red". I tend to categorize automatically into "scarlet" and "crimson" (too many hours spent with oil paints and pastels over too many decades), rarely ever seeing anything as "merely red", and that division is sometimes blurred by monitor calibration (or, rather, the lack of same). It's not so much that I see different things than other people with good colour vision, just that I have learned to do a primary categorization of "red" with two buckets instead of one.
