How can one change color for "z" in SG3d

Hello,

I am using Grass 4.1 on an Indigo 2. In SG3d I am able to use ascii x,y,z
files (long/lat/water depth) to get raster files which I use to as the display
file and also for the color. What I need to do is reverse the order of the
colors that indicate, in my case, water depth. What is the procedure for
doing this?
