如何更改页面内的背景颜色

我有一份如下所示的一页文档。我希望背景颜色为绿色，然后我想将其更改为黄色。可以吗？

\documentstyle{article}

\begin{document}

\pagecolor{green}
I would like the background color of the page until here would be green.\\

\pagecolor{yellow}
Then from now on, I would like the background would be yellow.

\end{document}

从当前位置更改页面颜色的命令不需要知道确切位置。相反，可以绘制一个大的彩色矩形。以下示例\paperwidth向左移动并绘制一个宽度2\paperwidth和高度为的矩形\paperheight。无论页面上的当前位置如何，这都会覆盖剩余页面的整个部分。不需要额外运行 LaTeX。

绘制矩形后，\pagecolor里面使用\afterpage也可以获取实际页面颜色的改变。

该命令支持或包括可选参数\changepagecolor的完整语法。\color\pagecolor

\documentclass{article}
\usepackage[a6paper, hmargin=12mm, vmargin=12mm, includefoot]{geometry}
\usepackage{lipsum}

\usepackage{color}
\usepackage{afterpage}

\makeatletter
% Macro \changepagecolor has the same syntax as \pagecolor or \color
% with an optional argument and a mandatory argument.
\newcommand*{\changepagecolor}{%
  \@ifnextchar[\@changepagecolor@i\@changepagecolor@ii
}
% Case: \changepagecolor[...]{...}
\def\@changepagecolor@i[#1]#2{%
  \@changepagecolor@do{[{#1}]{#2}}%
}
% Case: \changepagecolor{...}
\newcommand*{\@changepagecolor@ii}[1]{%
  \@changepagecolor@do{{#1}}%
}
\newcommand*{\@changepagecolor@do}[1]{%
  % Fill the remaining space with a colored rule
  \begingroup
    \offinterlineskip
    \hbox to 0pt{%
      \kern-\paperwidth
      \vtop to 0pt{%
        \color#1%
        \hrule width 2\paperwidth height \paperheight
        \vss
      }%
      \hss
    }%
  \endgroup
  % Set page color for the next page
  \afterpage{\pagecolor#1}%
}
\makeatother

\begin{document}
\pagecolor{green}
\lipsum[2]
\changepagecolor{yellow}
\lipsum[3]
\lipsum[4]
\end{document}

第 1 页 第2页

这是一种使用tikzmark并避免需要手动指定每个矩形高度的方法。

\documentclass{article}
\usepackage{tikz,kantlipsum}
\usetikzlibrary{tikzmark}
\begin{document}

\pagecolor{green}
\kant[1]

\tikzmark{here}
\begin{tikzpicture}[overlay, remember picture, inner sep=0pt, outer sep=0pt]
  \fill [yellow] (current page.west |- {pic cs:here}) rectangle (current page.south east);
\end{tikzpicture}

\kant[2]

\end{document}

黄绿色

\documentclass{article}
\usepackage{tikz}
\newcommand{\amount}{6in}   %%<---- adjust
\begin{document}
\begin{tikzpicture}[remember picture,overlay]
  \fill[green] ([yshift=-\amount]current page.north west) rectangle (current page.north east);
  \fill[yellow] (current page.south west) rectangle ([yshift=-\amount]current page.north east);
\end{tikzpicture}
I would like the background color of the page until here would be green.\\

\vspace{4in}
Then from now on, I would like the background would be yellow.

\end{document}

在此处输入图片描述

通常情况下，必须在定义所有 \tikzmarks 之后绘制 tikz 图片，在这种情况下，它们将绘制在文本之上，因此对于此问题，必须小心地从上到下进行操作。但是，使用页面钩子，可以在页面布局之后但在页面输出之前绘制 tikz 图片，这会将文本置于顶部。

\documentclass{article}
\usepackage{everypage}
\usepackage{tikzpagenodes}

\begin{document}
\tikz[remember picture,overlay]{\path coordinate(A);}%
I would like the background color of the page until here would be green.\\

Then from now on, I would like the background would be yellow.

\AddThispageHook{\begin{tikzpicture}[remember picture,overlay]
  \fill[color=green] (A -| current page.west) rectangle (current page.north east);
  \fill[color=yellow] (A -| current page.west) rectangle (current page.south east);
\end{tikzpicture}}
\end{document}
