r.colors.stddev(1)

NAME
r.colors.stddev

DESCRIPTION
r.colors.stddev set raster map color rules based on standard deviations from a map's mean value, either as a continuous color gradient or in color bands per standard deviation from the mean.

With the color band option values less that 1 S.D. from the mean are colored green, within 1-2 S.D. are colored yellow, within 2-3 S.D. are colored red, and beyond 3 S.D. are colored black.

For a differences map there is an option to lock the center of the color table at zero. Values more than two S.D. below the mean will be colored blue; values below the mean but less than 2 S.D. away will transition to white, and above the mean the colors will simularly transition to full red at +2 S.D.
