I can't help on the first bit but I would guess that they would follow
the same format as minclookup (man minclookup for more). As an example
here is the spectral colourmap that can be passed to minclookup


harold:Downloads$ cat ~rotor/lib/luts/spectral
0.00 0.0000 0.0000 0.0000
0.05 0.4667 0.0000 0.5333
0.10 0.5333 0.0000 0.6000
0.15 0.0000 0.0000 0.6667
0.20 0.0000 0.0000 0.8667
0.25 0.0000 0.4667 0.8667
0.30 0.0000 0.6000 0.8667
0.35 0.0000 0.6667 0.6667
0.40 0.0000 0.6667 0.5333
0.45 0.0000 0.6000 0.0000
0.50 0.0000 0.7333 0.0000
0.55 0.0000 0.8667 0.0000
0.60 0.0000 1.0000 0.0000
0.65 0.7333 1.0000 0.0000
0.70 0.9333 0.9333 0.0000
0.75 1.0000 0.8000 0.0000
0.80 1.0000 0.6000 0.0000
0.85 1.0000 0.0000 0.0000
0.90 0.8667 0.0000 0.0000
0.95 0.8000 0.0000 0.0000
1.00 0.8000 0.8000 0.8000

For a discrete colourmap the first column would be an integer set from 0-255
