+% With Version 1.7, this package also supports an optional |color| package option. If that option
+% is present, then |xcolor| is loaded and the |\regfield| and |\regfieldb| macros support an
+% optional first argument that is used as fill color for the boxes drawn by |\framebox|. Internally,
+% |\colorbox| is used to provide this functionality.
+%
+% Repeating our example from earlier, but with some fill colors specified:
+% \begin{verbatim}
+% \begin{register}{H}{Color Example}{0x250}% name=example
+% \label{colexample}%
+% \regfield{FIFO depth}{6}{58}{{random}}%
