带有可变宽度的额外白色边框（独立）

Question

当我使用以下代码生成两个彩色框时：

\documentclass[border={0pt 0pt 0pt 0pt}]{standalone} % left bottom right top
\usepackage{varwidth}
\usepackage{xcolor}
\usepackage[xparse]{tcolorbox}

\begin{document}
\tcbset{left skip=0pt, boxrule=0pt,
        size=fbox, sharp corners,
        colframe=black, width=0.75\linewidth}
\begin{varwidth}{0.5\linewidth}
  \begin{tcolorbox}[colback=red!30]
    Some random text
  \end{tcolorbox}
  \begin{tcolorbox}[colback=blue!30]
    Some more random text...

    With a line skip!
  \end{tcolorbox}
\end{varwidth}

\end{document}

我得到以下结果：

无论我做什么，都无法摆脱左边的白色边框。

任何帮助，将不胜感激。
