DESCRIPTION

42       r.colors.stddev set raster map color rules based on standard deviations
43       from a map’s mean value, either as a continuous color  gradient  or  in
44       color bands per standard deviation (S.D.) from the mean.
45
46       With  the  color  band option values less that 1 S.D. from the mean are
47       colored green, within 1-2 S.D. are colored yellow, within 2-3 S.D.  are
48       colored red, and beyond 3 S.D. are colored black.
49
50       For  a  differences  map  there  is an option to lock the center of the
51       color table at zero. Values more than two S.D. below the mean  will  be
52       colored  blue;  values  below  the  mean but less than 2 S.D. away will
53       transition to white, and above the mean the colors will simularly tran‐
54       sition to full red at +2 S.D.
