How do I fill color outside the page border created by tikz?

Question

This is how I am making the border:

\documentclass{article}
\usepackage{background}
\usepackage{tikz}
\usetikzlibrary{calc}
\backgroundsetup{angle = 0, scale = 1, vshift = -2ex,
  contents = {\tikz[overlay, remember picture]
    \draw [rounded corners = 15pt, line width = 2pt, color = black]
           ($(current page.north west)+(2cm,-2cm)$)
           rectangle ($(current page.south east)+(-2,2)$);}}
\begin{document}
Hello World!
\end{document}

Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for the users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem. — samcarter_is_at_topanswers.xyz, Mar 12 '24 at 12:19

As a quick workaround, you could use a coloured page and fill your frame with white:

\documentclass{article}
\usepackage{background}
\usepackage{tikz}
\usetikzlibrary{calc}
\pagecolor{red}
\backgroundsetup{angle = 0, scale = 1, vshift = -2ex, opacity=1,
  contents = {\tikz[overlay, remember picture]
    \path [fill=white,rounded corners = 15pt, line width = 2pt, draw=black]
           ($(current page.north west)+(2cm,-2cm)$)
           rectangle ($(current page.south east)+(-2,2)$);}}
\begin{document}
Hello World!
\end{document}

If you need a transparent background, e.g. because you use the pdfpages package, you could use the inverted clipping method from https://tex.stackexchange.com/a/290508/36296

\documentclass{article}
\usepackage{background}
\usepackage{tikz}
\usetikzlibrary{calc}
\tikzset{
    clip even odd rule/.code={\pgfseteorule}, % Credit to Andrew Stacey 
    invclip/.style={
        clip,insert path=
            [clip even odd rule]{
                reset cmrectangle(\maxdimen,\maxdimen)
            }
    }
}
\backgroundsetup{
  angle = 0, 
  scale = 1, 
  vshift = -2ex,
  opacity= 1,
  contents = {
    \begin{tikzpicture}[overlay, remember picture]
      \draw [rounded corners = 15pt, line width = 4pt, color = black]
           ($(current page.north west)+(2cm,-2cm)$)
           rectangle ($(current page.south east)+(-2,2)$);
      \clip[invclip,rounded corners=15pt]   ($(current page.north west)+(2cm,-2cm)$) rectangle ($(current page.south east)+(-2,2)$);
      \fill[red] (current page.south west) rectangle (current page.north east);

    \end{tikzpicture}
  }
}
\begin{document}
Hello World!
\end{document}
