我希望能夠在考試批改的背景下重現這種環境。
我發現的一條線索是 bclogo 套件的用法。
但是，我想包括此處所示的突出顯示的 Python 程式碼，並且我想包括縮排線並根據範圍（縮排級別）對它們進行著色。
彩色演算法程式碼:

\KwIn{List of clauses}
\KwOut{The clauses are satisfiable}
\SetKwProg{Fn}{Function}{ is}{end}
\Fn{\textsc{IsSatisfiable}($C$)} {
\color{red} %<- my best attempt
$k\gets 0$ \;
\For {$i = 1$ \bf{to} $|C|$}
{
$c_i \gets $ $i$-th clause \;
$L \gets$ list of literals of $c_i$ \;
$k\gets f(k, L)$ \tcp{a miracle in polynomial time}
}

\If {$k$ is even} {

\Else {
\Return false
}
}
\end{algorithm}

對於Python程式碼，這裡是一個帶有套件的解決方案piton，需要使用LuaLaTeX（但不需要外部程式）。
