[GRASSLIST:3254] Re: colors for d.his

Wed Apr 21 10:37:31 EDT 2004

Just as a contrib.  This is what I often use for ecology and biogeography, for 
global and regional coverages:

Saturated colors:

-11000   black
-4000   0 0 102
-1000   0 102 178
-200    0 128 178
-100    0 204 204
-50     0 204 204
-0.3    0 255 255
1       0 127 0
200     51 178 0
500     153 178 0
1000    178 153 51
1500    178 178 102
4000    127 127 127
5000    white
10000   white

Unsaturated colors:

-11000  52 73 93
-6000   52 73 93
-1000   55 75 95
-200    70 90 100
-0.3    102 140 140
1       95 127 71
500     163 141 110
1500    153 153 153
5000    200 200 200
9000    white

(I find the unsaturated a little too dark and too saturated, I'll fix it 
someday I have time to give it some thought :)

Both try to present diffs in lowlands and shallow seas, the habitats of the 
organisms we usually work with, and for ecology altitude and depth 
differences mean far more the closer you are to sealevel, so the color ramps 
focus on that by being very steep close to sealevel. So diffs in depths and 
mountains are mostly toned down.
