Most higher primates (including humans) can see somewhere in the area of 
2.3 million discernible colors.

Even if the monitors and printers really could produce 8 bits per color 
(and they can't) we couldn't see them all as distinctly different.

In fact, to show one dot each of the full color spectrum available in 
the 8 bit/color (24 bit depth) one would have to cover an 11" x 17" 
piece of paper, edge to edge at 300 dpi.

That's a heck of a LOT of colors.
