- Colors generated by a computer (linear) do not match the logrithmic scale
- your eye perceives. So, while it can be argued that 16M is beyond our
- range, the SPECIFIC 16M that the computer generates are NOT. You can
- easily tell the difference between a 10, 15, and 25 watt lightbulb - but
- can you tell the difference between a 15000 and 15500 watt light?
- Doubtful. The computer creates each intensity on a linear scale which
- means that it's overkill at the highest intensity and not enough to fool
- your eye at the lowest. If the computer created MORE steps between the
- lower and medium intensities and less at high intensities then you might
- get all the colors you want at 24-bits. This is not an easy nor
- worthwhile task with a digital machine when adding 8 bits is so much simpler.
-
- Given certain images, I can tell the difference between 24-bit and 32-bit
- color. I *can* see banding on a 24-bit color screen IF those colors are
- the ones the human eye is more sensitive to - specifically, if they
- contain green.

- (Our sensitivity to green is the reason that a 16-bit color screen gives
- 5-bits per gun to red and blue, and 6-bits to green)
