You win our eternal (well, temporary) gratitude for stimulating this
fascinating discussion (which, of course, deserves its own item).

Re #21: when I was working with filters, etc, I knew a central wavelength
for the seven "colors", in order to talk about filter choices more easily.
The boundary values are, in the context of seven "colors", not even colors
(since they are between two colors). 

Re #22: I don't understand yet...is the "256 colors" coding an 8 bit word?
If so, it can only code for 256 colors, not 256 of each of the three guns,
which would require either 3 8 bit words, or one 10 bit word. I guess I
don't understand the lookup scheme for the 24 bit color map. In addition,
a lot of the combinations from the 24 bit map are the same color - just
different intensities. Is intensity coded separately?
