When using the color
package in its switch form (\color
cf. \textcolor
), things can get confused using certain packages, with footnotes, and with section headings. The section headings issue was discussed in another of my questions but, even with the \zcolor
robust command definition suggested by David Carlisle (the color author) there, this still causes problems with footnotes, and the longtable
and hyperref
packages.
See the LaTeX source below:
(a) Footnotes from coloured text lose their colour.
(b) hyperref
URLs within footnotes get the colour back! (This doesn't happen if using the url
package instead.)
(c) Floating longtables can/will get the color of text on the page they float to, even when defined in a non-coloured area. (Using table
and tabular
doesn't have this problem. I used the afterpage
package to force the table to be on the next page, and assume the problem still exists if it 'naturally' did.)
\documentclass[11pt,a4paper,twoside,notitlepage]{article}
%\usepackage{url} % URLs in footnotes consistent (no color) if use this instead
\usepackage{hyperref}
\usepackage{breakurl}
\usepackage[usenames,dvips]{color}
\usepackage{lipsum}
\usepackage{afterpage}
\usepackage{longtable}
\newcommand{\startToDo}{\color{Purple}}
\newcommand{\stopToDo}{\color{Black}}

What about footnote weirdness?\footnote{A profound footnote that should be
colored with a URL:
\url{http://wibblewobble.org}.}

%\begin{table}
%\begin{tabular}{ccc}
a & b & c \\
d & e & f \\
\caption{An astonishing table that shouldn't be coloured.}
%\end{tabular}
%\end{table}
\end{longtable}
}

I guess my question is:
Can my use of color
be 'fixed' to work robustly in all such scenarios?
(David's answer to my other question suggests color
is fundamentally problematic in such contorted constructs, and can't be 'fixed' itself.)
As the \startToDo
and \stopToDo
(custom) macros suggest, I use color
to mark-up to-do text. I'll ask a separate question about better alternatives (that avoid these colour issues).
