I defined a custom color for use with the track-changes package changes.sty. It works well except when I add a comment argument to the optional arguments of a command.
Can anyone confirm getting this behaviour and suggest a work-around?
The MWE is:
\documentclass[14pt]{extarticle}
\usepackage[margin=1.0in]{geometry}
\usepackage{color}
\definecolor{darkgreen}{rgb}{0.0,0.6,0.1} % Custom colour
\usepackage{changes}
\definechangesauthor[color=magenta]{AA}
\definechangesauthor[color=darkgreen]{BB} % Author BB uses custom colour
\begin{document}
% No comment or custom colour: WORKS FINE
Quick \added[id=AA]{brown} fox jumped.
% Comment but no custom colour: WORKS FINE
Quick \added[id=AA,comment={Not red}]{brown} fox jumped.
% No comment or custom colour: WORKS FINE
Quick \added[id=BB]{brown} fox jumped.
% Comment and custom colour: GENERATES ERROR (Line 19)
Quick \added[id=BB,comment={Not red}]{brown} fox jumped.
% ! Package xcolor Error: Undefined color model `'.
%
% See the xcolor package documentation for explanation.
% Type H <return> for immediate help.
% ...
%
% l.19 Quick \added[id=BB,comment={Not red}]{brown}
% fox jumped.
\end{document}
P.S. I tried to pretty up the example by giving wide margins for the comment arguments, but changes.sty doesn't seem to use those margins. A search of the PDF documention for "width" doesn't turn up anything that I recognize as a parameter for controlling the width of the margin balloons for containing the comments.
