使用 tcolorbox 生成一个看起来像 beamers block 环境的框

Question

我想用 tcolorbox 模拟 beamer 的块环境，因为后者对我来说似乎更灵活。我有几个最终需要创建的框式环境。我的第一次（失败的）尝试是模拟块环境颜色。代码如下。

我的 consoleBox 环境很接近，但颜色不太正确（太暗）。我以为 beamer 皮肤可能会让我获得 beamer 颜色，但如果可以，我不确定它使用的是哪种颜色。

请提供指点！

\documentclass[aspectratio=169]{beamer}
\usepackage[skins]{tcolorbox}
\usecolortheme{rose}
\newenvironment{consoleBox}
{\usebeamercolor{block title}\usebeamercolor{block body}%
  \begin{tcolorbox}[sharp corners,frame empty,coltitle=block title.fg,%
    colbacktitle=block title.bg,colback=block body.bg,title=Console,%
    boxrule=0.5pt,arc=4pt,left=0pt,right=6pt,top=6pt]}
  {\end{tcolorbox}}
\begin{document}
\begin{frame}
\frametitle{Problem}

  \begin{block}{Console}
    This is the desired appearance.
  \end{block} 

  \begin{consoleBox}
    This is close but not quite right.  The body background is way too
    dark and the title background is a little too dark.
  \end{consoleBox}

  \begin{tcolorbox}[skin=beamer,title=Console]
    This is an attempt with skins...one might think that the beamer
    skin would use the beamer color theme?
  \end{tcolorbox}


\end{frame}
\end{document}

Ignasi 在其评论中已经链接的答案的简化版本：

\documentclass[aspectratio=169]{beamer}
\usepackage[skins]{tcolorbox}
\usecolortheme{rose}

\newtcolorbox{consoleBox}[2][]{%
    colbacktitle=structure.fg!20!white, 
    coltitle=structure.fg, 
    colback=block title.bg!40!white,
    title=#2,
    boxrule=0pt,
    sharp corners,
    #1
}  
  
\begin{document}
\begin{frame}
\frametitle{Problem}

  \begin{block}{Console}
    This is the desired appearance.
  \end{block} 

  \begin{consoleBox}{Console}
    This is close but not quite right.  The body background is way too
    dark and the title background is a little too dark.
  \end{consoleBox}

\end{frame}
\end{document}

使用新的 tcolorbox 内部主题可以进一步简化代码 (https://www.ctan.org/pkg/beamertheme-tcolorbox）。此主题将自动从您正在使用的主题中获取颜色、形状等：

\documentclass[aspectratio=169]{beamer}
\usepackage[skins]{tcolorbox}
\usecolortheme{rose}

\useinnertheme{tcolorbox}

\newtcolorbox{consoleBox}[2][]{%
    title=#2,
    #1
}  

\begin{document}
\begin{frame}
\frametitle{Problem}

  \begin{block}{Console}
    This is the desired appearance.
  \end{block} 

  \begin{consoleBox}{Console}
    This is close but not quite right.  The body background is way too
    dark and the title background is a little too dark.
  \end{consoleBox}

\end{frame}
\end{document}
