画出特定部分

我怎样才能将特定部分涂成白色？

这里是代码：

在这种情况下，这很容易。你已经有了所有的路径，所以你可以说

\draw[fill=red!20] (2,2) to[out=30,in=180] (4,3) |- (3,4)
 to[out=270,in=60] (2,2);

如您所见，您只需要在反向路径中交换in和的角色即可。out

只需用所需颜色填充矩形

\fill[orange] (0,0) rectangle (4,4);

在其他fill命令之前draw。

我已修改了代码，使其变得最少。

\documentclass{scrbook}
\usepackage{tikz}
\begin{document}
\begin{figure}
    \centering
    \begin{tikzpicture}
    \draw[fill=orange] (0,0) rectangle (4,4);
    \draw[fill=blue!20] (0,0) -- (2,2) to[out=30,in=180] (4,3) -- (4,0);
    \draw[fill=yellow!20] (0,0) -- (2,2) to[out=60,in=270] (3,4) --(0,4);

    \draw[dashed] (-0.2,2)-- (2,2)
        (2,0)-- (2,2);
    \draw  (0,0) -- (2.3,2.3) ; 
    \draw[->] (2,2) -- (2,4.2);
    \draw[->] (2,2) -- (4.2,2);

    \draw[] (4.2,1.8) node {\tiny $ \epsilon_{\tiny A}$}  
        (1.8,4.2) node {\tiny $\epsilon_{\tiny B}$};  
    \node (c) at (3,1) { \tiny prova };
    \node (b) at (1,3) { \tiny prova };
    \node[]at (1,1){\tiny Antagonistic };
    \node[]at (1,0.7){\tiny Sector };
    \node[rotate=45]at (3,3){\tiny prova };
    \end{tikzpicture}
    \caption{capt}
      \label{dise}
\end{figure}
\end{document}
