<div>No, it won't work with pdftex. It's a dvips thing. This will also work:</div>
<div> </div>
<div>dvips -o ttemp.ps ttemp.dvi</div>
<div>
<div>ps2pdf ttemp.ps</div>
<div> </div>
<div>You're welcome. I'm glad it worked for you.</div>

<div style="font-family: Lucida Sans;">If I set TeXShop to use Tex + DVI instead of Pdftex, it does work.<br/>
Thank you.<br/>

<div>Not sure if this will help. I wasn't aware that eplain could (or should?) be used with LaTeX. At any rate,</div>
<div> </div>
<div>\input colordvi</div>
<div>\Red{abc}, \Blue{def}, $\ldots$</div>
<div> </div>
<div>works with plain and eplain. I'm not sure whether eplain is needed. colordvi.tex belongs to dvips. You can use dvipdfmx to make pdf.</div>
