노이즈 성분이 있는 임의의 점

Question

지정된 영역을 점점으로 채우는 방법이 궁금합니다. 녹색 영역을 임의의 녹색 점으로 채우고 빨간색 영역 대신 빨간색 임의 점으로 흰색 영역을 파란색 임의 점으로 채우고 싶습니다. 내 코드는 다음과 같습니다.

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations.pathreplacing}
%\usepackage{xcolor,pict2e}% to allow any radius

  \tikzset{pics/myarc/.style args={inner #1 and outer #2 with fill #3}{
  code={
    \draw[very thick, #1] (1,0) arc (0:90:1cm);
    \draw[very thick] (0,1) -- (0,2);
    \draw[very thick, #2] (0,2) arc (90:0:2cm);
    \draw[very thick] (2,0) -- (1,0);
    \fill[#3] (1,0) arc (0:90:1cm) -- (0,2) arc (90:0:2cm) -- cycle;
  }
}}
\begin{document}
\begin{tikzpicture}
\draw[very thick,<->] (-6,0) -- (6,0)node[anchor=north west] {$x$};
\pic [draw,very thick, rotate=-45]      {myarc={inner blue and outer blue with fill green!}};
\pic [draw, very thick, rotate=45]      {myarc={inner blue and outer blue with fill white}};
\pic [draw, very thick, rotate=135]      {myarc={inner blue and outer blue with fill red!40}};
\pic [draw, very thick, rotate=225]      {myarc={inner cyan and outer blue with fill white}};
\end{tikzpicture}

\end{document}
