DESCRIPTION

52       r.blend blends color components of 2 raster maps by a  specificed  per‐
53       centage of the first map.
54

EXAMPLE

56       Blending  the aspect map with the elevation map for a shaded map (North
57       Carolina sample dataset):
58       g.region raster=aspect -p
59       r.blend first=aspect second=elevation output=elev_shade_blend
60       d.mon wx0
61       d.rgb blue=elev_shade_blend.b green=elev_shade_blend.g red=elev_shade_blend.r
