So, this may or may not have anything whatsoever to do with reality, and it 
certainly has nothing to do with Argyll. But it *does* have to do with the 
physiology of the eye and of the gamut of emissive displays, and I know 
there're lots of people here knowledgeable and interested in such things.

It just occurred to me that it might be practical to create a display with a 
gamut that encompasses the entirety of human vision by using not three but five 

Keep the three red, green, and blue primaries we're familiar with, but also add 
a fourth in the near infrared and a fifth in the near ultraviolet, both right 
at (or barely beyond?) the very edge of the limits of perception.

There would be safety concerns with the UV, of course, but I wouldn't think it 
would need either a high frequency or a high intensity.

Am I nuts? Ignorant?
