Just a few notes:

The "old VGA displays" had 256 simultaneous colors - I had one of those 8-bit beauties.
You mean EGA - which had 16 (of 64) simultaneous colors.
or maybe you should have picked CGA (3 simultaneous colors) [let's forget the old monochromes].

The 'more than 3 colors in the visible spectrum' concept is not really correct. The entire electromagnetic spectrum, of which the visible is a pathetically narrow slice, is (practically) a continuum. That, however, is peripheral to the question at hand.

It's more like a linear algebra construct: color-space, because of our r/g & b/y perceptior cells, can be defined completely as a 3 dimensional construct: 3 vectors, which we can roughly call primary colors, can create the entire color space. Judicious selection of these basis sets allows for such tasks as printing, color photography, and LCD's.

This, however, I reemphasize, is a perceptual description. The (colored) light stimulates the (cone) cells, which we'll initially approximate as binary sensors. The pattern is translated to the colors within the brain. I will admit that I am not sure, to what extent, cone-cells exhibit an analog response. Can they supply more than simple t/f for a given color stimulation? I lean towards yes, they can, but feel too lazy to look it up right now.

The human eye/brain signal processing is remarkable (a memory from a college physics class, after spending a while on optics). It eye should hardly work at all, but it does.
