Will Robertson's "<i>X</i>Ǝ<i>TEX reference guide</i>" reads (in part)<br>
<br>
<blockquote type="cite">color=RRGGBB[TT]<br>
Triple pair of hex values to specify the colour in RGB space, with an
optional<br>
value for the transparency.</blockquote>
<br>
However, experimenting with all possible values from "00" to "FF"<br>
for the transparency byte seems to have zero effect, in that the<br>
second element laid down completely obscures whatever lies<br>
beneath it. What am I missing, please ?<br>
