在 TikZ 中生成带有叠加数字的矩阵数组

Question

我怎样才能在 中生成如下图形TikZ？我还想在所有单元格中叠加所需的数字。到目前为止，我已经能够生成类似的图形，但在所有背景矩阵中具有相同的颜色，并且无法控制单元格条目：

\documentclass{article}
\usepackage{tikz}

\begin{document}
\begin{tikzpicture}
\pgfmathdeclarerandomlist{choices}{{U}{0}}
\foreach \z in {0,2.5,5}{ 
\begin{scope}[xshift=\z*0.02cm] 
\foreach \x in {0,...,3}{ 
\foreach \y in {0,...,3}{ 
\node[fill=yellow,minimum size=1cm-\pgflinewidth,draw] (n-\x-\y-\z) at (\x+.5,\y+.5,\z) {\pgfmathrandomitem{\mynum}{choices}\mynum}; } }    \end{scope} } 
\end{tikzpicture}
\end{document}

提前致谢！

使用matrix：

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{matrix}

\begin{document}
\begin{tikzpicture}
  \pgfmathdeclarerandomlist{choices}{{U}{0}}
  \foreach \z/\c in {0/blue,2.5/blue!66,5/blue!33}{ 
    \begin{scope}[xshift=\z] 
      \foreach \x in {0,...,3}{ 
        \foreach \y in {0,...,3}{ 
          \node[fill=\c,minimum size=1cm-\pgflinewidth,draw]
          (n-\x-\y-\z) at
          (\x,\y,\z) {\pgfmathrandomitem{\mynum}{choices}\mynum}; } }
    \end{scope} } 
\end{tikzpicture}

\begin{tikzpicture}
  \foreach \s/\c in {0cm/blue,1cm/blue!66,2cm/blue!33}{
    \begin{scope}[xshift=-\s,yshift=-\s]
    \matrix [matrix of nodes, ampersand replacement=\&,
    nodes={rectangle, anchor=center, draw=black!40, fill=\c,
      minimum width=1cm, minimum height=1cm},
    row sep=-\pgflinewidth, column sep=-\pgflinewidth,
    nodes in empty cells]
    {
      1 \& 2 \& \& \\
      \& \& \& \\
      \& \& \& \\
      \& \& \& \\
    };
  \end{scope}
}
\end{tikzpicture}
\end{document}
