\begin{itemize}
  \item The outer frame is drawn in \textcolor{DIC161s}{100\% DIC161}.
  \item The title background uses \textcolor{DIC161s!80}{80\% DIC161}.
  \item The content background uses a subtle \textcolor{DIC161s!10}{10\% DIC161} tint.
  \item Even the drop shadow is rendered using a \textcolor{DIC161s!30}{30\% DIC161} tint!

\section{Backward Compatibility Tests}

\subsection*{\textsf{colorspace} package macros}

This page tests the dummy backward compatibility macros for the \textsf{colorspace} package.
They should produce no visible output and cause no compilation errors.
\onelineskip

Testing \verb|\pagecolorspace|...
\pagecolorspace{DIC161s} % Should silently do nothing
\onelineskip

Testing \verb|\resetpagecolorspace|...
\resetpagecolorspace % Should silently do nothing
\onelineskip

If the document compiles successfully and this page renders without errors, the backward compatibility wrappers are working perfectly.
