[Tex/LaTex] Changing border colors of all tables in a document

colortables

I have a document full of tables (think 8-10 tables) – already written. Some are tabulars, others are longtables. I do not want to substantially change the existing code.

What is the fastest way (in terms of markup) to convert the colors of border and frame lines from black to a specified color? I have xcolor loaded?

This is for a class file, and if a single redefinition of the internals of tabular or longtable could do it, that would be perfect.

MWE:

\documentclass{article}
\usepackage{longtable}
\usepackage{xcolor}
\usepackage{lipsum}
\usepackage{hyperref}

\begin{document}

\lipsum[1]

\begin{tabular}{llll}\hline
Some & Thing & Here & Now \\\hline
1 & 2 & 3 & 4 \\\hline
\end{tabular}

\lipsum[2]
\begin{longtable}[l]{|p{2.5cm}|p{5.5cm}|p{6cm}} \hline
Word & Play & Table \\\hline
This & is & now \\\hline
That & was & then \\\hline
\end{longtable}

\lipsum[2]

\end{document}

\begin{tabular}{llll}\hline
Some & Thing & Here & Now \\\hline
1 & 2 & 3 & 4 \\\hline
\end{tabular}

\lipsum[2]
\begin{longtable}[l]{|p{2.5cm}|p{5.5cm}|p{6cm}} \hline
Word & Play & Table \\\hline
This & is & now \\\hline
That & was & then \\\hline
\end{longtable}

\lipsum[2]

[Tex/LaTex] Changing \eqref colors in Beamer

Just redefine \eqref to incorporate the color change:

\documentclass[10pt]{beamer}

\usepackage{amsfonts}

\usetheme{Warsaw}
\usecolortheme{whale}

\makeatletter
\renewcommand\eqref[1]{%
  \textup{\usebeamercolor[fg]{structure}\tagform@{\ref{#1}}}%
}

\begin{document}

\begin{frame}{}

\begin{equation}
y'=p(x)y\label{eqn1}
\end{equation}
\eqref{eqn1} is a linear differential equation of first order.

\end{frame}

\end{document}

[Tex/LaTex] Changing Colors of Document

Colors can be set via package color. It is important to set the color to white in the preamble. Then package color uses this color as \normalcolor. LaTeX uses this color at various places. For example, it resets the color in header and footers to make them independent from the color that is active at the time the output routine is called.

\documentclass{article}
\usepackage{blindtext}
\usepackage{color}
\pagecolor{black}
\color{white}

\begin{document}
\blinddocument
\end{document}

Switching colors

Also the colors can be switched on a page level. Some pages can be put as white on black and others as black on white.

The page color can be turned off by \nopagecolor. This is only supported by few drivers (pdftex.def, dvips.def). For other drivers, \pagecolor{white} can be used.

The \normalcolor is more tricky, the following example hacks into the internals to define \whiteonblack and \blackonwhite, which also changes the \normalcolor accordingly.

\documentclass{article}
\usepackage{blindtext}
\usepackage{color}

\makeatletter
\let\default@color@black\current@color
\newcommand*{\blackonwhite}{%
  \newpage
  \let\default@color\default@color@black
  \normalcolor
  \@ifundefined{no@page@color}{%
    \pagecolor{white}%
  }{%
    \nopagecolor
  }%
}
\color{white}
\let\default@color@white\current@color
\newcommand*{\whiteonblack}{%
  \newpage
  \let\default@color\default@color@white
  \normalcolor
  \pagecolor{black}%
}
\pagecolor{black}
\makeatother

\begin{document}
\blinddocument
\blackonwhite \blinddocument
\whiteonblack \blinddocument
\end{document}
