如何更改自定义环境中的标题颜色

Question

我正在使用 tcolorbox 包来构建类似自定义定理的环境。

\documentclass{article}
\usepackage{xcolor}
\usepackage{tcolorbox}
\tcbuselibrary{theorems,skins,hooks}

\definecolor{myblue}{RGB}{0, 61, 116}

\newcounter{algorithmcounter}
\newtcbtheorem[number within=section]{algorithminner}{\textcolor{myblue}{Algorithm}}
{%
    enhanced,
    colback=blue!10,
    frame hidden,
    boxrule=0pt,
    borderline west={2pt}{0pt}{myblue},
    sharp corners,
    detach title,
    before upper=\tcbtitle\par\smallskip,
    coltitle=black!85,
    fonttitle=\bfseries\sffamily,
    description font=\mdseries,
    separator sign none,
    segmentation style={solid, black!85},
}{th}

\newenvironment{algorithm}[1]
{\stepcounter{algorithmcounter}\begin{algorithminner}{#1}{algorithm-\arabic{section}-\arabic{algorithmcounter}}}
{\end{algorithminner}}

\begin{document}

\section{Example Section}

\begin{algorithm}{Example Algorithm}
This is an example algorithm.
\end{algorithm}

\end{document}

这是我编译后得到的结果。 但我想将数字计数器的颜色（“算法 1.1”）也更改为 myblue。我尝试使用，coltitle=myblue但它改变了整个标题的颜色。我希望“示例算法”保持默认的黑色。

任何帮助都将受到赞赏。

Answer 1

使用coltitle=myblue和description color=black!85。

（也删除明确的\textcolor。）
