See r.colors for display colours...
you should define your color rules...
Alternatively you can create/modify your color file (same name of your
raster map) under the colr folder of your mapset.
e.g.:
% -20 20
-20:255:255:255 -10:255:255:255
-10:255:0:0 10:0:255:0
10:255:255:255 20:255:255:255
these represent in withe cells with values lower -10 and upper +10, and
from red to green in between
lines mean:
(from -20 to -10 ramp between 255:255:255 and 255:255:255)-.>withe
(from -10 to 10 ramp between 255:0:0 and 0:255:0)->red to green
(from 10 to 20 ramp between 255:255:255 and 255:255:255) -.>withe
