the "differences" color rule looks like this: 0% blue 0 white 100% red also, have a look at r.colors.stddev's -z flag, as that makes the red and blue above equally scaled. (so if range was -1 to 100, the -1 would only be a very light blue instead of full-blue. > I want to define a color table where: > all negative values are blue > all zeros are green > all positive values are red. assuming negative/positive values always exist, try: 0% blue 0 blue 0 green 0 red 100% red if you want a hard step, repeating works well for two colors next to each other, not sure if it will go for 3. You might want to make -0.0001 thru 0.0001 as green if it really is a full floating point spectrum. Also need to verify that hard-step behaviour isn't broken in grass7. ?, Hamish _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
