Poor PostScript is probably your problem. If Preview doesn't see the proper
header and page information in the document it will not display it in color.
I usually add the following to a trashy PS document to get Preview to display
it properly.

Add/change the following at the top of the doc.

%!PS-Adobe-2.0
%%EndComments
%%BeginProlog

Put the following just before the first page begins.

%%EndProlog
%%Page: 1 1

Put the following before the rest of the pages (usually after showpage's)
where x is the proper page number.

%%Page: x x

That is usually enough to make Preview happy.

Note that depending on the consistency of the output, you can probably
automate these steps in a shell script (I've got one for PATRAN on the Cray).

Hope that helps.
