How to use color declarations in titles?

Question

How can I use color declarations when setting the title of a document?

I tried

\title{\color{blue} Colors in typesetting}

but I get an error from LaTeX.

Update: The error reads as followed:

doc.tex:89: Argument of \reserved@a has an extra }.
<inserted text> 
            \par 
l.89 \begin{document}

Can I define a declaration or an environment which works inside \title? Or is there a way to enhance the definition of \title to accommodate declarations?

Update 2: To give more context, the base class pandoc uses here is beamer, but it draws in a lot of packages. (beamer itself behaves correct as the standard classes.)

Note: For technical reasons(*) I do not want to use

\title{\textcolor{blue}{Colors in typesetting}}

so, as stated above, it must be a color declaration.

(*) I really use pandoc to generate the TeX document from markdown and parameter-taking commands like \command{text} will skip "text" if I convert the markdown document to any other output format.

Answer 1

I'm sure there is a package for that, but here is a solution based on redefining the maketitle command (for the article class).

Create a style file (I saved as titlecolor.sty) with the following content (I copied this from the book.cls file and add the \color command to the title, you can change the format):

 \renewcommand\maketitle{\begin{titlepage}%
  \let\footnotesize\small
  \let\footnoterule\relax
  \let \footnote \thanks
  \null\vfil
  \vskip 60\p@
  \begin{center}%
    {\LARGE \color{blue}{\@title} \par}%
    \vskip 3em%
    {\large
     \lineskip .75em%
      \begin{tabular}[t]{c}%
        \@author
      \end{tabular}\par}%
      \vskip 1.5em%
    {\large \@date \par}%       % Set date in \large size.
  \end{center}\par
  \@thanks
  \vfil\null
  \end{titlepage}%
  \setcounter{footnote}{0}%
  \global\let\thanks\relax
  \global\let\maketitle\relax
  \global\let\@thanks\@empty
  \global\let\@author\@empty
  \global\let\@date\@empty
  \global\let\@title\@empty
  \global\let\title\relax
  \global\let\author\relax
  \global\let\date\relax
  \global\let\and\relax
}

Put \usepackage{titlecolor} in your document:

\documentclass{article}
    \usepackage{xcolor} % You need this also of course
    \usepackage{titlecolor}

\title{My title in Blue}

\begin{document}
\maketitle

Text....
\end{document}

Now you will get a coloured title.

Answer 2

For standard classes there's the titling package.

After the edit to the question, the class used here is beamer. In this case, the answer is really simple since beamer provides an easy way to change the color attributes for the title:

\documentclass{beamer}

\setbeamercolor{title}{fg=red,bg=blue}
\title{The Title}

\begin{document}

\begin{frame}
\maketitle
\end{frame}

\end{document}

The result:

In

\setbeamercolor{title}{fg=red,bg=blue}

fg stands for foreground and bg for background. In my example I changed both for illustration purposes, but ou can change only one of them.
