<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>
