\section{Library 'skins'}\label{sec:skins}
The library is loaded by a package option or inside the preamble by:
\begin{dispListing}
\tcbuselibrary{skins}
\end{dispListing}
This also loads the package |tikz| \cite{tantau:2010c}. Typically but not necessarily,
the following skins use |tikz| instead of |pgf|.
\subsection{Technical Overview and Core Package Option Keys}\label{sec:skincorekeys}
From a technical point of view, a \emph{skin} is a style definition for the
appearance of a |tcolorbox|. The core package provides some additional
option keys for skins but only a single skin called \refSkin{standard}.
The 'skins' library adds several more skins. To change a skin, only one
option from the core package has to be set.
\begin{docTcbKey}{skin}{=\meta{name}}{style, no default, initially \texttt{standard}}
Sets the current skin to \meta{name}. This is a style definition which sets all the following
keys, i.\,e.\ for many use cases there is nothing more to do.
\begin{dispExample}
\tcbset{colback=Salmon!50!white,colframe=FireBrick!75!black,
width=(\linewidth-8mm)/2,before=,after=\hfill,equal height group=ske}
\begin{tcolorbox}[adjusted title=My title]
This is my content.
\end{tcolorbox}
\begin{tcolorbox}[skin=beamer,beamer,adjusted title=My title]
This is my content.
\end{tcolorbox}
\end{dispExample}
\end{docTcbKey}
\begin{marker}
On first read, you may skip the rest of this subsection and proceed to
Subsection \ref{subsec:addstyleoptions} on page \pageref{subsec:addstyleoptions}.
All following keys in this subsection are automatically set by the selected skin
and you may never have to temper with them.
Nevertheless, they can be used after a skin was selected to modify
this skin.
\end{marker}
\begin{docTcbKey}{skin first}{=\meta{name}}{style, no default, initially \texttt{standard}}
If the box is set to be \refKey{/tcb/breakable} and \emph{is} broken actually,
then the skin for the \emph{first} part of the break sequence
is set to \meta{name}, see Subsection \ref{subsec:breaksequence} on page \pageref{subsec:breaksequence}.
Typically, this key is set by a \refKey{/tcb/skin}.
\end{docTcbKey}
\begin{docTcbKey}{skin middle}{=\meta{name}}{style, no default, initially \texttt{standard}}
If the box is set to be \refKey{/tcb/breakable} and \emph{is} broken actually,
then the skin for the \emph{middle} parts (if any) of the break sequence
is set to \meta{name}, see Subsection \ref{subsec:breaksequence} on page \pageref{subsec:breaksequence}.
Typically, this key is set by a \refKey{/tcb/skin}.
\end{docTcbKey}
\begin{docTcbKey}{skin last}{=\meta{name}}{style, no default, initially \texttt{standard}}
If the box is set to be \refKey{/tcb/breakable} and \emph{is} broken actually,
then the skin for the \emph{last} part of the break sequence
is set to \meta{name}, see Subsection \ref{subsec:breaksequence} on page \pageref{subsec:breaksequence}.
Typically, this key is set by a \refKey{/tcb/skin}.
\end{docTcbKey}
\begin{docTcbKey}{graphical environment}{=\meta{name}}{no default, initially \texttt{pgfpicture}}
Sets the graphical environment for the |tcolorbox| to \meta{name}.
Feasible values are |pgfpicture| and |tikzpicture| or environments which
inherit from one of these two. This key is set by a \refKey{/tcb/skin} and
may seldom be used directly.
\end{docTcbKey}
The skin of a |tcolorbox| is drawn by up to four \emph{engines}.
Afterwards, the text content is drawn which is not part of a skin.
The four steps are:
\begin{enumerate}
\item The \emph{frame} of the box.
\item The \emph{interior} of the box. The interior of a box with title is
drawn differently from a box without title.
\item The \emph{segmentation} (line) of the box, if there is a lower part.
\item The \emph{title area} of the box, if there is a title.
\end{enumerate}
Every engine for the up to four steps can be set to one of the following types:
\begin{enumerate}
\item |standard|: the original code from the core package.
\item |path|: a |tikz| path which can be controlled by options.
\item |pathfirst|: a |tikz| path which can be controlled by options.
\item |pathmiddle|: a |tikz| path which can be controlled by options.
\item |pathlast|: a |tikz| path which can be controlled by options.
\item |freelance|: arbitrary user code.
\end{enumerate}
%\clearpage
\begin{docTcbKey}{frame engine}{=\meta{name}}{no default, initially \texttt{standard}}
Sets the \emph{frame} drawing engine for a box to \meta{name}.
Typically, this key is set by a \refKey{/tcb/skin}.
Feasible values for \meta{name} are:
\begin{itemize}
\item |standard|: the original code from the core package,
\item |path|: a |tikz| path which is controlled by \refKey{/tcb/frame style},
\item |pathfirst|: a |tikz| path which is controlled by \refKey{/tcb/frame style},
\item |pathmiddle|: a |tikz| path which is controlled by \refKey{/tcb/frame style},
\item |pathlast|: a |tikz| path which is controlled by \refKey{/tcb/frame style},
\item |freelance|: arbitrary user code which is given by \refKey{/tcb/frame code}.
\end{itemize}
\end{docTcbKey}
\begin{docTcbKey}{interior titled engine}{=\meta{name}}{no default, initially \texttt{standard}}

\item |path|: a |tikz| path which is controlled by \refKey{/tcb/interior style},
\item |pathfirst|: a |tikz| path which is controlled by \refKey{/tcb/interior style},
\item |pathmiddle|: a |tikz| path which is controlled by \refKey{/tcb/interior style},

\end{itemize}
\end{docTcbKey}
\begin{docTcbKey}{interior engine}{=\meta{name}}{no default, initially \texttt{standard}}

Feasible values for \meta{name} are:
\begin{itemize}
\item |standard|: the original code from the core package,
\item |path|: a |tikz| path which is controlled by \refKey{/tcb/interior style},
\item |pathfirst|: a |tikz| path which is controlled by \refKey{/tcb/interior style},
\item |pathmiddle|: a |tikz| path which is controlled by \refKey{/tcb/interior style},
\item |pathlast|: a |tikz| path which is controlled by \refKey{/tcb/interior style},
\item |freelance|: arbitrary user code which is given by \refKey{/tcb/interior code}.
\end{itemize}
\end{docTcbKey}
\begin{docTcbKey}{segmentation engine}{=\meta{name}}{no default, initially \texttt{standard}}
Sets the \emph{segmentation} (line) drawing engine for a box to \meta{name}.
Typically, this key is set by a \refKey{/tcb/skin}.
Feasible values for \meta{name} are:
\begin{itemize}
\item |standard|: the original code from the core package,
\item |path|: a |tikz| path which is controlled by \refKey{/tcb/segmentation style},

\end{itemize}
\end{docTcbKey}
\begin{docTcbKey}{geometry nodes}{\colOpt{=\meta{boolean value}}}{default |true|, initially |false|}
If set to |true|, up to four |tikz| nodes are defined for a |tcolorbox|
which are named |frame|, |interior|, |segmentation|, and |title|. These nodes
describe the boundaries of the equally named parts of a |tcolorbox|.
They are used by all engines of type |path| and they may be used by engines
of type |freelance|. Typically, this key is set by a \refKey{/tcb/skin}.
\begin{dispExample}
\tcbset{colback=Salmon!50!white,colframe=FireBrick!75!black,
width=(\linewidth-8mm)/2,before=,after=\hfill,equal height group=geon}
\begin{tcolorbox}[adjusted title=The title]
The upper part.\tcblower The lower part.
\end{tcolorbox}
\begin{tcolorbox}[adjusted title=The title,skin=freelance,
frame code={\path[draw=red,fill=red!25]
(frame.south west) rectangle (frame.north east);},
interior titled code={\path[draw=blue,fill=blue!25]
(interior.south west) rectangle (interior.north east);},
segmentation code={\path[draw=green,fill=green!25]

The upper part.\tcblower The lower part.
\end{tcolorbox}
\end{dispExample}
\end{docTcbKey}

\subsection{Style Option Keys}\label{subsec:addstyleoptions}
The following style options are applicable for all skins which
use engines of type |path|, |pathfirst|, |pathmiddle|, or |pathlast|.
Especially, the skin \refSkin{enhanced} supports \emph{all} of them
and \refSkin{standard} \emph{none}.
\begin{docTcbKey}{frame style}{=\meta{\texttt{\upshape tikz} keys}}{style, no default}
The \meta{\texttt{\upshape tikz} keys} are used inside the |tikz| path command
for drawing the \emph{frame} of the box.\\
This option is available if the \refKey{/tcb/frame engine} is set to
|path|, |pathfirst|, |pathmiddle|, or |pathlast|.
It is \emph{not} available for |standard| and it \emph{may} be
applicable for |freelance|.
\begin{dispExample*}{sbs,lefthand ratio=0.66}
\tcbset{colback=red!5!white,fonttitle=\bfseries}
\begin{tcolorbox}[enhanced,title=My title,
frame style={left color=red!75!black,
right color=blue!75!black}]
This is a \textbf{tcolorbox}.
\tcblower
This is the lower part.
\end{tcolorbox}
\end{dispExample*}
\end{docTcbKey}
\begin{docTcbKey}{frame hidden}{}{style, no value}
This is a shortcut for |frame style={draw=none,fill=none}|.
Depending on the skin, this option switches off the drawing of the
frame.
\begin{dispExample*}{sbs,lefthand ratio=0.66}
\tcbset{colback=red!5!white,colframe=red!75!black,
fonttitle=\bfseries,coltitle=black}
\begin{tcolorbox}[enhanced,title=My title,
frame hidden]
This is a \textbf{tcolorbox}.
\tcblower
This is the lower part.
\end{tcolorbox}
\end{dispExample*}
\end{docTcbKey}
\begin{docTcbKey}{interior style}{=\meta{\texttt{\upshape tikz} keys}}{style, no default}
The \meta{\texttt{\upshape tikz} keys} are used inside the |tikz| path command
for drawing the \emph{interior} of the box. They are used for the titled
and for the untitled version as well.\\
This option is available if the \refKey{/tcb/interior titled engine}
or \refKey{/tcb/interior engine} is set to
|path|, |pathfirst|, |pathmiddle|, or |pathlast|.
It is \emph{not} available for |standard| and it \emph{may} be
applicable for |freelance|.
\begin{dispExample*}{sbs,lefthand ratio=0.66}
\tcbset{colframe=red!75!black,fonttitle=\bfseries}
\begin{tcolorbox}[enhanced,title=My title,
interior style={left color=red!20!white,
right color=yellow!50!white}]
This is a \textbf{tcolorbox}.
\tcblower
This is the lower part.
\end{tcolorbox}
\end{dispExample*}
\end{docTcbKey}
\clearpage
\begin{docTcbKey}{interior hidden}{}{style, no value}
This is a shortcut for |interior style={draw=none,fill=none}|.
Depending on the skin, this option switches off the drawing of the
interior.
\begin{dispExample*}{sbs,lefthand ratio=0.66}
\tcbset{frame style={top color=red!20!white,
bottom color=red!20!white!75!black},
fonttitle=\bfseries,coltitle=black}
\begin{tcolorbox}[enhanced,title=My title,
interior hidden]
This is a \textbf{tcolorbox}.
\tcblower
This is the lower part.
\end{tcolorbox}
\end{dispExample*}
\end{docTcbKey}
\begin{docTcbKey}{segmentation style}{=\meta{\texttt{\upshape tikz} keys}}{style, no default}
The \meta{\texttt{\upshape tikz} keys} are used inside the |tikz| path command
for drawing the \emph{segmentation} line of the box.\\
This option is available if the \refKey{/tcb/segmentation engine}
is set to |path|.
It is \emph{not} available for |standard| and it \emph{may} be
applicable for |freelance|.
\begin{dispExample*}{sbs,lefthand ratio=0.66}
\tcbset{colback=red!5!white,colframe=red!75!black,
fonttitle=\bfseries}
\begin{tcolorbox}[enhanced,title=My title,
segmentation style={double=white,draw=blue,
double distance=1pt,solid}]
This is a \textbf{tcolorbox}.
\tcblower
This is the lower part.
\end{tcolorbox}
\end{dispExample*}
\end{docTcbKey}
\begin{docTcbKey}{segmentation hidden}{}{style, no value}
This is a shortcut for |segmentation style={draw=none,fill=none}|.
Depending on the skin, this option switches off the drawing of the
segmentation line.
\begin{dispExample*}{sbs,lefthand ratio=0.66}
\tcbset{colback=red!5!white,colframe=red!75!black,
fonttitle=\bfseries}
\begin{tcolorbox}[title=My title,
enhanced,segmentation hidden]
This is a \textbf{tcolorbox}.
\tcblower
This is the lower part.
\end{tcolorbox}
\end{dispExample*}
\end{docTcbKey}
\clearpage
\begin{docTcbKey}{title style}{=\meta{\texttt{\upshape tikz} keys}}{style, no default}
The \meta{\texttt{\upshape tikz} keys} are used inside the |tikz| path command
for drawing the \emph{title area} of the box.\\
This option is available if the \refKey{/tcb/title engine} is set to
|path|, |pathfirst|, |pathmiddle|, or |pathlast|.
It is \emph{not} available for |standard| and it \emph{may} be

\subsection{Watermark Option Keys}\label{subsec:watermarks}
The following watermark options are applicable for all skins which
use |tikzpicture| as \refKey{/tcb/graphical environment}.
Therefore, the skin \refSkin{standard} does not support these watermarks,
but all other skins, e.\,g.\ \refSkin{enhanced}.
\begin{marker}
The watermark options rely on the more general overlay options described in
Section \ref{subsec:overlays} from page \pageref{subsec:overlays}.
Therefore, \emph{watermarks} and \emph{overlays} cannot be used mixed.
But a mixture is possible with the 'hooks' library, see Section \ref{sec:hooks}.
\end{marker}
\begin{docTcbKey}{watermark text}{=\meta{text}}{no default, initially unset}
Writes some \meta{text} in the center of the interior region of a |tcolorbox|.
This \meta{text} is written \emph{after} the
frame and interior are drawn and \emph{before} the text content is drawn.
It is zoomed or stretched according the values of
\refKey{/tcb/watermark zoom} or \refKey{/tcb/watermark stretch}.
\begin{dispExample}
\tcbset{colback=red!5!white,colframe=red!75!black,fonttitle=\bfseries}
\begin{tcolorbox}[enhanced,title=My title,watermark text=My Watermark]
\lipsum[1]
\tcblower

\end{tcolorbox}
\end{dispExample}
\end{docTcbKey}
\begin{docTcbKey}{watermark text on}{=\meta{part} is \meta{text}}{no default, initially unset}
This option writes some \meta{text} in the center of the interior region of a |tcolorbox|
as described for \refKey{/tcb/watermark text}.
But this is done only for boxes named \meta{part} of a break sequence, see
\refKey{/tcb/breakable}.\\
Feasible values for \meta{part} are:
\begin{itemize}
\item |broken|: all broken box parts,
\item |unbroken|: unbroken boxes only,
\item |first|: first parts of a break sequence,
\item |middle|: middle parts of a break sequence,
\item |last|: last parts of a break sequence,
\item |unbroken and first|: unbroken boxes and first parts of a break sequence,
\item |middle and last|: middle and last parts of a break sequence.
\end{itemize}
\end{docTcbKey}
\clearpage
\begin{docTcbKey}{watermark graphics}{=\meta{file name}}{no default, initially unset}
Draws an external picture referenced by \meta{file name}
in the center of the interior region of a |tcolorbox|.
The picture is drawn \emph{after} the
frame and interior are drawn and \emph{before} the text content is drawn.
It is zoomed or stretched according the values of
\refKey{/tcb/watermark zoom} or \refKey{/tcb/watermark stretch}.
\begin{dispExample}
\tcbset{colback=red!5!white,colframe=red!75!black,fonttitle=\bfseries}
\begin{tcolorbox}[enhanced,title=My title,watermark graphics=Basilica_5.png,

\end{docTcbKey}
\begin{docTcbKey}{watermark graphics on}{=\meta{part} is \meta{file name}}{no default, initially unset}
This option draws a picture referenced by \meta{file name} in the center of the interior region of a |tcolorbox|
as described for \refKey{/tcb/watermark graphics}.
But this is done only for boxes named \meta{part} of a break sequence, see
\refKey{/tcb/breakable}.\\
Feasible values for \meta{part} are:
\begin{itemize}
\item |broken|: all broken box parts,
\item |unbroken|: unbroken boxes only,
\item |first|: first parts of a break sequence,
\item |middle|: middle parts of a break sequence,
\item |last|: last parts of a break sequence,

\begin{docTcbKey}{watermark tikz}{=\meta{graphical code}}{no default, initially unset}
Draws the given |tikz| \meta{graphical code}
in the center of the interior region of a |tcolorbox|.
The code is executed \emph{after} the
frame and interior are drawn and \emph{before} the text content is drawn.
The result is zoomed or stretched according the values of
\refKey{/tcb/watermark zoom} or \refKey{/tcb/watermark stretch}.
\begin{dispExample}
\tcbset{colback=red!5!white,colframe=red!75!black,fonttitle=\bfseries}

This option draws the given |tikz| \meta{graphical code} in the center of the interior region of a |tcolorbox|
as described for \refKey{/tcb/watermark tikz}.
But this is done only for boxes named \meta{part} of a break sequence, see
\refKey{/tcb/breakable}.\\
Feasible values for \meta{part} are:
\begin{itemize}

\begin{docSkin}{enhanced}
This skin translates the drawing commands of the core package into |tikz|
path commands. Therefore, it allows all |tikz| high level options for
these paths and has more flexibility compared to the \refSkin{standard} skin.
You pay for this with some prolonged compilation time.
The |tikz| path options can
be given with the option keys
\refKey{/tcb/frame style},
\refKey{/tcb/interior style},
\refKey{/tcb/segmentation style}, and
\refKey{/tcb/title style}.

\subsection{Skin 'freelance'}
\begin{docSkin}{freelance}
This skin gives full freedom for the appearance of the |tcolorbox|.
All drawing engines are set to type |freelance|; they use the |tikz| package
and compute the \refKey{/tcb/geometry nodes}.
This skin is useful for boxes which should differ much from the normal
appearance. Note that this difference has to be programmed by the user.
The drawing code can be given
with the following option keys. As default value, the code from the |standard|
skin is set.

\subsection{Skin family 'bicolor'}
\begin{docSkin}{bicolor}
This skin is quite similar to the \refSkin{standard} and \refSkin{enhanced} skin.
But instead of a segmentation line, the optional lower part of the box is filled with a
different color or drawn with a different style.
\begin{tcolorbox}[skintable=bicolor]

\refKey{/tcb/title engine}: \> |path|
\end{tabbing}
\end{tcolorbox}
\begin{itemize}
\item The most basic usage of this skin is to set the background color of
the lower part by \refKey{/tcb/colbacklower} and all other options like for
the \refSkin{standard} skin.
\begin{dispExample}
\begin{tcolorbox}[skin=bicolor,title=The title,
colframe=FireBrick!75!black,colback=Salmon!50!white,colbacklower=Salmon]
The upper part.
\tcblower
The lower part.
\end{tcolorbox}
\end{dispExample}
\item The more advanced usage of this skin is to apply the \refKey{/tcb/frame style}
and the \refKey{/tcb/interior style} like for
the \refSkin{enhanced} skin. Also, the \refKey{/tcb/segmentation style} can be
used, but it is applied to the whole lower part.
\begin{dispExample}
\begin{tcolorbox}[skin=bicolor,title=The title,
frame style={top color=FireBrick,
bottom color=FireBrick!15!white,draw=black},
interior style={left color=Salmon,right color=Salmon!50!white},
