Jacob,

With some pointers from Howard, I found this segment of code in
bindColorAttribute() in maputil.c:

     attribute->red = atoi(tokens[0]);
     attribute->blue = atoi(tokens[1]);
     attribute->green = atoi(tokens[2]);


I think this is responsible.  If you are building from source, try just
changing it to the more obvious organization.  I'd also suggest you
file a bug in Trac on the issue we will see if there is a subtle reason
for this, or it's just a typo.

To file bugs you need an OSGeo Userid.  The pointer to get an osgeo
userid which you can use to login with is under the title "Important
Notice" on the http://trac.osgeo.org/mapserver page.  The same userid
can be used for other OSGeo services like subversion, and other
trac instances (like GDAL's).

Best regards,
