[mapserver-users] Recoloring a raster...

[Daniel Morissette]

Maybe I misunderstood the question, is it not what raster class 
expressions are for?

https://mapserver.org/input/raster.html#classifying-rasters

   CLASS
     NAME "red -> blue"
     EXPRESSION ([red] = 255 AND [green] = 0 AND [blue] = 0)
     STYLE
       COLOR 0 0 255
     END
   END
