Hi was able to put some color in the file using a2ps
You can download a2ps from macports.

a2ps -R --column=1 --no-header --font-size=20 --pretty-print=js --highlight-level=heavy --pro=color --left-title=ITITLE1 --right-title=ITITLE2 -o temp.ps file.txt

_________________________________________________________________

Now this produces a file with only some of the words colored.

In order to make all the words colored I edited the js stylesheet.
Actually I created my own stylesheet and called it js2
You have to use awk ans sed commands to put the words from your file into the js2 file.

Here are the steps one by one.
1. First create a dummy file (js2.ssh) in the following directory opt/local/share/a2ps/sheets/ using command.

sudo vi /opt/local/share/a2ps/sheets/js2.ssh

2. Next link the file to your real js2.ssh file in your working directory
ln -s /opt/local/share/a2ps/sheets/js2.ssh ./js2.ssh

3. Next write a script to create js2.ssh file in your working directory here is a copy of my own called makejs2

This script is run by ./makejs2 file.txt > js2.ssh

3. Next run the a2ps command again:
a2ps -R --column=1 --no-header --font-size=20 --pretty-print=js --highlight-level=heavy --pro=color --left-title=ITITLE1 --right-title=ITITLE2 -o temp.ps file.txt

That Should do it!!!!!!!!!!!!!
Enjoy
