我已按自己的喜好更改了颜色。我想要的只是指向的箭头Descriptions。
答案1
我不确定您想把描述放在哪里，是在 itemize 环境中还是如图所示放在图片内？我认为在 itemize 环境中一切都会有点紧凑，所以我更喜欢另一种选择。如果是这样的话，有一个解决方案。
我改变了所有的代码，但我认为这种方式更简单：
\documentclass[compress]{beamer}

\usetikzlibrary{3d}
\xdefinecolor{O} {rgb}{0.85, 1.0, 0.3}
\xdefinecolor{OO} {rgb}{0.67, 1.0, 0.3}
\xdefinecolor{OOO} {rgb}{0.43, 1.0, 0.3}
\xdefinecolor{OOOO}{rgb}{0.27, 1.0, 0.3}
\newcommand{\tile}[7] % position (x axis), width, height, color, front label, number of letters, description
{%
\begin{scope}[canvas is xy plane at z=#3]
\draw[fill=#4!70!black] (#1,0) rectangle (#1-#2,#3);
\foreach[count=\xi] \i in{#5} % for each letter in the word
{%
\pgfmathsetmacro\h{#3*(#6+0.5-\xi)/#6} % height for the letter
\node[scale=0.3*#3] at (#1-0.5*#2,\h) {\i};
}
\end{scope}
\draw[canvas is xz plane at y=#3,fill=#4!70] (#1,0) rectangle (#1-#2,#3);
\draw[canvas is yz plane at x=#1,fill=#4] (0,0) rectangle (#3,#3);
\draw[thick,red,rounded corners,->] (#1-0.5*#2,#3,0.7*#3) |- (5,#3+0.5) node [right] {#7};
}
