Bob,
I'd recommend just re-rendering the raster off-line for performance
reasons, but if data management makes that difficult have a look at the
"Classifying Rasters" section of
http://www.mapserver.org/input/raster.html#how-are-rasters-added-to-a-map-file.
And Mapserver can only classify a single 8-bit band (grey or paletted),
even if your image is say 3 band RGB.
Best Regards,
Brent Fraser

I have a geotiff raster which represents forested lands. I'd like it
to display in green. I put in a Style section and specified a color,
but try as I might, it always displays in grayscale. It is an 8-bit
unsigned TIFF file.
Below is the layer specification:
LAYER
NAME "ForestLands"
GROUP "ForestLands"
TYPE RASTER
STATUS on
DATA "/mapserver_data/StreamBarriers/forestland06.tif"
METADATA
"wms_srs" "EPSG:4326 EPSG:26919 EPSG:26983 EPSG:26984 EPSG:102113"
"wms_name" "ForestLands"
"wms_server_version" "1.1.1"
"wms_format" "image/png"
END
CLASS
NAME "Forest"
STYLE
COLOR 0 250 0
END
END
END
