[Tex/LaTex] How to change color of some particular environment for entire document

colorenvironmentsfontsmath-modeverbatim

I want to change color of particular environment in document.
For example wherever I found verbatim environment or equation environment appears in my tex file. With some global settings, I want to change it to some particular color effect should be limited to that document.

For example all the verbatim should change to yellow background. All of the math mode should have text color red.

Doing it for each of the text or modifying the environment is possible, how ever I am interested in setting it once in preamble.

There is no general solution. It depends on the enviroment. Some have dedicated hooks, other you will have to redefine. With verbatim you could e.g. change \verbatim@font. For math you could e.g. use everymath - but as you can see in the example it can have side effects as math is sometimes used in unexpected places like url.

\documentclass{article}
\usepackage{xcolor, url}
\makeatletter
\renewcommand\verbatim@font{\color{red}\normalfont\ttfamily}
\makeatletter

\everymath{\color{green}}
\begin{document}
blub

\begin{verbatim}
abx
\end{verbatim}

blub


$x=y$

bla

\(sum=c\)

\url{www.abc}
\end{document}

[Tex/LaTex] Change color and background behind text of all ‘description’ environments

Unfortunately you can not change the style of environments as easy as it is possible using CSS with HTML. However, you can redefine description or define your own variant which adds the color commands.

To set the background color you can use my adjustbox package:

\documentclass{article}
\usepackage{xcolor}
\usepackage{adjustbox}

\newenvironment{cdescription}{%
  \begin{adjustbox}{minipage=\linewidth,bgcolor=blue,vspace=\smallskipamount}
    \begin{description}
      \color{red}%
}{%
    \end{description}
  \end{adjustbox}
}

\begin{document}

Text before

\begin{cdescription}
    \item[Hello] World
    \item[Example] Item
\end{cdescription}

text after

\end{document}

If you want to redefine description instead you can save the old definition away and use it internally.

\let\olddescription\description
\let\endolddescription\enddescription
\renewenvironment{description}{%
  \begin{adjustbox}{minipage=\linewidth,bgcolor=blue,vspace=\smallskipamount}
    \begin{olddescription}
      \color{red}%
}{%
    \end{olddescription}
  \end{adjustbox}
}

If you want to set the colors for every environment simply add [2] after the environment name (e.g., \newenvironment{cdescription}[2]{%) and replace the color names with #1 and #2 in the definition.

The right keys to modify the exampleblock environment are:

block title example for the title;
block body example for the body of the block.

Here is a complete example:

\documentclass{beamer}

\usetheme{Frankfurt}
% Define my settings
\definecolor{mygreen}{cmyk}{0.82,0.11,1,0.25}
\setbeamertemplate{blocks}[rounded][shadow=false]
\addtobeamertemplate{block begin}{\pgfsetfillopacity{0.8}}{\pgfsetfillopacity{1}}
\setbeamercolor{structure}{fg=mygreen}
\setbeamercolor*{block title example}{fg=blue!50,
bg= blue!10}
\setbeamercolor*{block body example}{fg= blue,
bg= blue!5}


\begin{document}

\begin{frame}{Frame title}
\begin{block}{Block title}
Hello
\end{block}
\begin{exampleblock}{ExampleBlock title}
Hello
\end{exampleblock}
\end{frame}
\end{document}
