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.
