Hi,
 
sounds like the greyscale-rasters consume the whole color palette. 
If you use MS 4.0 you could try the COLOR_MATCH_THRESHOLD-option on the
responsible greyscale-raster (I don't know if this option also exists in
MS 3.x).
 
LAYER
   NAME "xyz"
   TYPE RASTER   
   PROCESSING "COLOR_MATCH_THRESHOLD=3" # <= insert this
   [...]
END
 
HTH,

I have been displaying some raster images in my map, and started
noticing that some datasets cause the rest of my features to display in
greyscale, ignoring the colors set. This includes point symbols, labels
and outlines.
 
Does anyone know why this might happen? This seems to happen using JPGs
or TIFs of the same area. As well, I've processed down the raster images
from 8-bit color down to greyscale (according to
http://mapserver.gis.umn.edu/data2/wilma/mapserver-users/0211/msg00594.h
tml
<http://mapserver.gis.umn.edu/data2/wilma/mapserver-users/0211/msg00594.
html> ), but this didn't work.
 
Thanks,
Chris
