% \part{Usage}
%
% \section{Installation}
%
% \subsection{Required Packages}
% The \xmpkg\ package requires relatively updated packages. These packages are 
% \kvopkg\footnote{The \kvopkg\ package is available at
% \url{https://www.ctan.org/pkg/kvoptions}} and \xcolorpkg\footnote{The 
% \xcolorpkg\ package is available at \url{https://www.ctan.org/pkg/xcolor}}, 
% which are included in any popular \TeX\ distribution. Both are loaded without 
% options.
%
% \subsection{Installing \xmpkg}
% Once the \xmpkg\ package is released in \href{http://www.ctan.org}{CTAN}, 
% users should be able to install it from the \TeX\ distribution package manager
% available in their PC. However, if you need to install this package 
% manually, you should run:
% ^^A
% \begin{verbatim}
%   latex xcolor-material.ins\end{verbatim}
% ^^A
% and copy the generated file |xcolor-material.sty| to a path where \LaTeX\ can 
% find it. To generate the documentation run the following 
% command twice.
% ^^A
% \begin{verbatim}
%   pdflatex xcolor-material.dtx\end{verbatim}
%
% \section{Loading \xmpkg}
% Simply add the package declaration somewhere in the document preamble.
% ^^A
% \begin{verbatim}
%   \usepackage{xcolor-material}\end{verbatim}
%
% If you want to load the \kvopkg\ and \xcolorpkg\ packages with some 
% options, you can specify those options using the |\PassOptionsToPackage| 
% command \emph{before} loading \xmpkg, or by loading those packages with their 
% options \emph{before} loading the \xmpkg\ package.
%
% \subsection{Package Options}
% The \xmpkg\ currently offers only one option,
% \begin{description}
%   \item[\opt{prefix}|=|\meta{prefix}] Defines the prefix for all color names
%   defined in the Google Material Color Palette; this is used for namespacing
%   purposes. The default prefix is ``|Material|''.
% \end{description}
% The main purpose of this option is to avoid conflicts with other existent 
% color definitions. The |prefix| option allows custom prefix definition, e.g., 
% if you want to use the word `|myprefix|' as the color prefix, 
% then you must load the \xmpkg\ package with
% ^^A
% \begin{verbatim}
%   \usepackage[prefix=myprefix]{xcolor-material}\end{verbatim}
%
% \section{Using \xmpkg}
% The \xmpkg\ provides all colors specified in the Google Material Color 
% Palette, available at \url{https://material.google.com/style/color.html}, in 
% the global scope of the document. This package relies on the \xcolorpkg\ 
% package, and you should refer to its documentation for more details 
% about using colors inside the document.
%
% \subsection{Color Names}
% The Google Material Color Palette consists of 19 color palettes (each 
% for one base color) and two colors not included in any palette (|White| and 
% |Black|), together forming a list of 256 colors. Each individual palette 
% consists of 14 color variations of the base color, except for |Brown|, 
% |Grey|, and |Blue Grey| with 10. Every color variation has a number from the 
% list \texttt{\{50, 100, 200, 300, 400, 500, 600, 700, 800, 900\}}  for the 
% first ten colors or \emph{primary palette}, and from the list \texttt{\{A100, 
% A200, A300, A400\}} for the last four or \emph{secondary palette}. The names 
% of the base colors and their variations are listed in table 
% \ref{tab:colornames}. For a complete list of these palettes go to the section 
% \ref{sec:colorpalettes}.
%
% \begin{table}[b!]
%   \centering
%   \caption{Color names from the Google Material Color Palette and their 
%   variation palettes.} \label{tab:colornames}
%   \begin{tabular}{lc}
%      \hline
%      \textbf{Base Color} &amp; \textbf{Palettes}\\
%      \hline
%      \textcolor{MaterialRed}{|Red|} &amp; primary, secondary\\
%      \textcolor{MaterialPink}{|Pink|} &amp; primary, secondary\\
%      \textcolor{MaterialPurple}{|Purple|} &amp; primary, secondary\\
%      \textcolor{MaterialDeepPurple}{|Deep Purple|} &amp; primary, secondary\\
%      \textcolor{MaterialIndigo}{|Indigo|} &amp; primary, secondary\\
%      \textcolor{MaterialBlue}{|Blue|} &amp; primary, secondary\\
%      \textcolor{MaterialLightBlue}{|Light Blue|} &amp; primary, secondary\\
%      \textcolor{MaterialCyan}{|Cyan|} &amp; primary, secondary\\
%      \textcolor{MaterialTeal}{|Teal|} &amp; primary, secondary\\
%      \textcolor{MaterialGreen}{|Green|} &amp; primary, secondary\\
%      \textcolor{MaterialLightGreen}{|Light Green|} &amp; primary, secondary\\
%      \textcolor{MaterialLime}{|Lime|} &amp; primary, secondary\\
%      \textcolor{MaterialYellow}{|Yellow|} &amp; primary, secondary\\
%      \textcolor{MaterialAmber}{|Amber|} &amp; primary, secondary\\
%      \textcolor{MaterialOrange}{|Orange|} &amp; primary, secondary\\
%      \textcolor{MaterialDeepOrange}{|Deep Orange|} &amp; primary, secondary\\
%      \textcolor{MaterialBrown}{|Brown|} &amp; secondary\\
%      \textcolor{MaterialGrey}{|Grey|} &amp; secondary\\
%      \textcolor{MaterialBlueGrey}{|Blue Grey|} &amp; secondary\\
%      \textcolor{MaterialBlack}{|Black|} &amp; ---\\
%      \rowcolor{MaterialBlack}\textcolor{MaterialWhite}{|White|} &amp; 
% \textcolor{MaterialWhite}{---}\\
%      \hline
%    \end{tabular}
%\end{table}
%
% The name under which the \xmpkg\ package defines each Google Material color 
% has the form `\meta{prefix}\meta{base name}\meta{variation}', where
% \begin{itemize}
%   \item \meta{prefix} corresponds to the prefix set via the package option
%   |prefix|,
%   \item \meta{base name} is the official name of the base color (see table
%   \ref{tab:colornames}), and
%   \item \meta{variation} is the id number of the color variation, e.g., |50| 
% or |A100|.
% \end{itemize}
% For instance, by default (if a custom prefix is not defined), the |Blue 600| 
% color of the palette will be available in the document global scope as 
% ``|MaterialBlue600|''. Also, all base colors are representative of the 
% palettes' primary color and are available at the |500| variation or using 
% their color names, e.g., |MaterialBlue| or |MaterialBlue500| are the primary 
% color of the ``Material Blue Palette''.
%
% \subsection[Google Colors]{\google{} Colors}
% The \xmpkg\ package provides the Google Identity colors, which definitions 
% are available in the Google Design Blog at
% \url{https://design.google.com/articles/evolving-the-google-identity}. 
% The name under which these colors are defined has the form 
% `Google\meta{name}', where \meta{name} is a color name among 
% \textcolor{GoogleBlue}{|Blue|}, \textcolor{GoogleGreen}{|Green|}, 
% \textcolor{GoogleYellow}{|Yellow|}, and \textcolor{GoogleRed}{|Red|}. For 
% instance, if you want to use the Google Blue color you have to call for it 
% by using `|GoogleBlue|'.\\
%
% \noindent
% \colorsample{GoogleBlue}
% \colorsample{GoogleGreen}
% \colorsample{GoogleYellow}
% \colorsample{GoogleRed}\\
%
% \subsection{Useful macros}
% The \xmpkg\ provides some useful macros for printing color values, samples, 
% and palettes. Some of them maybe rely on other LaTeX packages that are 
% not loaded by default.
%
% \noindent
% \DescribeMacro{\printcolorvalue}
% \oarg{color model}\marg{color name}
%
% This macro can be used to print any color value. It has one mandatory 
% argument \meta{color name}, which specifies the color name which you want 
% to know its value. And one optional argument, \meta{color model} that 
% corresponds to the color model in which the value will be presented: |HTML|, 
% |RGB| and |cmyk| (|HTML| by default).
% \begin{table}[h!]
%   \centering
%   \begin{tabular}{lll}
%     |\printcolorvalue{MaterialBlue}| &amp; &amp; \textcolor{MaterialIndigo}{\printcolorvalue{MaterialBlue}}\\
%     |\printcolorvalue[RGB]{MaterialGrey}| &amp; &amp; \textcolor{MaterialIndigo}{\printcolorvalue[RGB]{MaterialGrey}}\\
%     |\printcolorvalue[cmyk]{orange}| &amp; &amp; \textcolor{MaterialIndigo}{\printcolorvalue[cmyk]{orange}}\\
%   \end{tabular}
%\end{table}
%
% \noindent
% \DescribeMacro{\colorsample}
% \oarg{color model}\oarg{text color}\oarg{box width}\marg{color name}\oarg{title}
%
% This macro allows you to draw color samples using a simple colorbox with
% text. It has one mandatory argument 
% \begin{itemize}
%   \item \meta{color name} which is the name of the color to be drawn,
% \end{itemize}
% and four optional arguments: 
% \begin{itemize}
%   \item \meta{color model} represents the color model in which the color will 
%   be presented (by default |HTML|),
%   \item \meta{text color} which specifies the color used for printing the 
%   text (by default |white|),
%   \item \meta{box width} specifies the box width (by default is |6.5em|), if 
%   it is \emph{empty} the default is passed, \item and \meta{title} which is 
%   the title of the color sample, if this argument is not passed the color 
%   name is taken.
% \end{itemize}
%
% To generate samples of the \google\ Colors showed above we can type 
% \begin{verbatim}
%   \colorsample{GoogleBlue} \colorsample{GoogleGreen}
%   \colorsample{GoogleYellow} \colorsample{GoogleRed}\end{verbatim}
%
% Other samples:
% ^^A 
% \begin{verbatim}
%   \colorsample[HTML][][black]{MaterialAmber50}
%   \colorsample{MaterialAmber}
%   \colorsample[RGB]{MaterialAmber600}
%   \colorsample{MaterialAmberA700}[Amber\\A700]\end{verbatim}
%
% \noindent
% \colorsample[HTML][][black]{MaterialAmber50}
% \colorsample{MaterialAmber}
% \colorsample[RGB]{MaterialAmber600}
% \colorsample{MaterialAmberA700}[Amber\\A700]
%
% \begin{verbatim}
%   \colorsample[cmyk][13em]{MaterialBlueGrey500}
%   \colorsample{purple}[\texttt{xcolor}\\ Purple]
%   \colorsample[RGB]{teal}[]
% \end{verbatim}
%
% \noindent
% \colorsample[cmyk][13em]{MaterialBlueGrey500}
% \colorsample{purple}[\texttt{xcolor}\\ Purple]
% \colorsample[RGB]{teal}[]\\
%
% \noindent
% \DescribeMacro{\colorpalette}
% \oarg{key-value arguments}\marg{color name}
%
% This macro is available only if the \tikzpkg\ package is loaded. It provides 
% a simple way to draw the Google Material Color Palettes in the same way as we 
% can find them into the \href{https://material.google.com/style/color.html}{Google 
% Style Blog}. It has one mandatory argument \meta{color name}, which specifies 
% the palette base color that will be used to draw its variation palette. 
% Optional arguments are provided in the form of key-value arguments and key 
% styles. A complete list of key-value arguments and styles is available at 
% table \ref{tab:keyvalue} and \ref{tab:styles} respectively. The \xmpkg\ 
% package relies on the \textsf{pgfkeys} package to provide key-value 
% arguments, for deeper knowledge about how to use key-value arguments look at 
% package documentation\footnote{The \textsf{pgfkeys} package is available at 
% \url{https://www.ctan.org/pkg/pgfkeys}.}.

% A printed palette is a stack of colorboxes that comprises three main 
% sections, one on top or |title colorbox| that is used for introducing the 
% palette with its primary variation, a |primary palette| in the middle and a 
% |secondary palette| at the bottom. With this macro, you can print out 
% all the palettes of the Google Material Colors, and with some configurations 
% you can print any color palette that you want in a fancy way as the Material 
% Palettes.
%
% For instance, the following commands produce a color palette for the 
% variations of the \xcolorpkg\ predefined |yellow| color between 10\,\% and 
% 100\,\%, and a custom palette by tricking the |\colorpalette| macro.
% \begin{verbatim}
%   \colorpalette[basic, title text color=black]{yellow}
%   \colorpalette[primary palette={yellow,blue,red,gray,black,purple}, 
%     secondary palette={yellow!20,blue!30,red!20,gray!40}, primary 
%     variation=orange, primary toggle at=blue]{}

% \section{Bug reports}
% The development version of this package is available at 
% \url{https://github.com/OSjerick/xcolor-material}. If you find bugs, have 
% feature suggestions or think of ways in which the \xmpkg\ package and its 
% documentation could be improved, please open a ticket in the GitHub 
% repository's issue tracker.
%
% \section{Acknowledgements}
% This package was inspired by the \textsf{xcolor-solarized} package, available
% at \url{https://www.ctan.org/pkg/xcolor-solarized}, then I have to thank 
% Julien Cretel its creator. Also, thanks to \google\ for such amazing color 
% palette.

% \part{Implementation}
%
% I have used the word `|XCM|' followed by an `|@|' character for namespacing
% purposes into the \xmpkg\ package source.
%
% \section{Required Packages}
% The \xmpkg\ requires the \xcolorpkg\ and \kvopkg\ packages, both are 
% loaded without any option.
%
%    \begin{macrocode}
\RequirePackage{xcolor}[2007/01/21]
\RequirePackage{kvoptions}[2011/06/30]
%    \end{macrocode}
%
% The \xcolorpkg\ package is used to define and provide every single color in 
% the \google\ Material Color Palette. The \kvopkg\ package supports package 
% options in a key-value format.
%
% \section{Package Options}
% Setting up \kvopkg\ configuration.
%
%    \begin{macrocode}
\SetupKeyvalOptions{
  family=XCM,
  prefix=XCM@
}
%    \end{macrocode}
%
% Declaring string option key `|prefix|':
%
%    \begin{macrocode}
\DeclareStringOption[Material]{prefix}[Material]
\DeclareDefaultOption{
  \OptionNotUsed
  \PackageError{xcolor-material}{Unknown `\CurrentOption' option.}
}
\ProcessKeyvalOptions*
%    \end{macrocode}
%
% Note that the default value for this key is `|Material|'. Note also that this
% package checks for valid options, if an invalid option is passed, a 
% PackageError will be thrown.
%
% \section{Color Definitions}
%
% \begin{macro}{\XCM@definecolor}
% I have taken the idea from the \textsf{xcolor-solarized} package of having a 
% convenient internal macro for color definitions.
%    \begin{macrocode}
\newcommand{\XCM@definecolor}[2]
  {\expandafter\definecolor\expandafter{\XCM@prefix #1}{HTML}{#2}}
%    \end{macrocode}
% \end{macro}
%
% Using this macro definition we can define all the \google\ Material colors
% as follows. Note that for every color in the palette, the |500|
% variation is the base color default as \google\ recommends for primary colors.
