I read somewhere, many years ago, where I can doubtless not find
it, that the human eye is capable of distinguishing about 10 million
shades of color.  (Presumably measured by taking two light sources
of known frequency some number of Angstroms apart, and seeing how
many people can distinguish them).

This means that when you get to 24 bits of color information, there
is no point in going any further.
