Wait a minute, what are you saying?

If you contend that you can resolve 24 bit color, then you are saying
(as far as I know) that you can tell FF FF FF from FF FF FE (all Hex).
If you can't then what do you mean by contending the human eye can
resolve 24 bit color?

I would test that theory by having a field of one color (say all red,
in my example FF 00 00, for Red, Green and Blue), and in that filed,
draw a solid image of, say, a circle with a color that is one bit off
(say FE 00 00) - if you can see the image, you can resolve the
difference - if you can't, you can't.
