       --ui
           Force launching GUI dialog

   Parameters:
       first=name [required]
           Name of first raster map for blending

       second=name [required]
           Name of second raster map for blending

       output=basename [required]
           Basename for red, green and blue output raster maps

       percent=float
           Percentage weight of first map for color blending

DESCRIPTION
       r.blend blends color components of 2 raster maps by a  specificed  per-
       centage of the first map.

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