Zufällige Punkte mit Rauschanteil

Question

Ich frage mich, wie ich einen bestimmten Bereich mit gepunkteten Punkten füllen kann. Ich möchte den grünen Bereich mit zufälligen grünen Punkten füllen und statt des roten Bereichs möchte ich ihn mit zufälligen roten Punkten und den weißen Bereich mit zufälligen blauen Punkten füllen. Hier ist mein Code:

\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}

Für jede Hilfe bin ich sehr dankbar. Danke

Mit regelmäßigen Punkten.

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations.pathreplacing,patterns}
%\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[pattern=dots,pattern color = #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 blue}};
\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 blue}};
\end{tikzpicture}

\end{document}

Die Randomisierung erfordert mehr Arbeit unddiese Frageund die Antworten sollten einen Hinweis geben.

Und hier ist ein Versuch mit der Strategie vondiese Antwort

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations.pathreplacing,patterns}
%\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);
    \clip (1,0) arc (0:90:1cm) -- (0,2) arc (90:0:2cm) -- cycle;
    \foreach \x in {1,...,300}
        {
            \pgfmathrandominteger{\a}{5}{300}
            \pgfmathrandominteger{\b}{5}{300}
            \pgfmathrandominteger{\c}{30}{30}
            \fill[#3] (0.01*\a,0.01*\b) circle (0.001*\c);
        };
  }
}}
\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 blue}};
\pic [draw, very thick, rotate=135]      {myarc={inner blue and outer blue with fill red!40}};
