Thanks for all the help! I wrote an operation to do color reduction to a
specified number of bits per channel, employing one out of a couple of
potential color compensation strategies.

I'm attaching it in case you want to use it for something, or re-use
parts of the code in a better operation.

I put a test image up at

http://hpjansson.org/temp/meadow-dithered.png

The picture has one bit per channel for a total of 8 colors, making it a
true retro experience. From left to right -- original, thresholding,
Bayer, F-S, covariant random and random dithering.
