打印 pstricks 节点后更改其选项

是否有可能更改打印节点的选项（例如颜色）？我用 multido 创建了很多节点，并想更改它们的外观。打印后有什么办法吗？

背景：我想规划生物实验，并用不同的颜色为圆圈（对应样本）着色，如下所示：

使用节点名称作为坐标，定义一个颜色系列，分为6个步骤：

\documentclass{scrartcl}
\usepackage{pst-node,multido}
\begin{document}
\def\AnzahlX{6}
\def\AnzahlY{4}
\def\AbstandX{1.57}
\def\AbstandY{1.47}
\def\Abstand{1.88}
\def\Durchmesser{1.5}
\pstFPdiv\Radius\Durchmesser{2}

\definecolorseries{foo}{rgb}{last}{red}{red!30!white}
\resetcolorseries[6]{foo}

\begin{pspicture}(0.7,-0.7)(12.9,-8.7)%
%Rahmen
\pspolygon(0,0)(12.8,0)(12.8,-8.2)(12.4,-8.6)(0,-8.6)%
%
%Beschriftung
\multido{\nX=\AbstandX+\Abstand,\iN=1+1}{\AnzahlX}{\rput(\nX,0.5){\iN}}%
\multido{\nY=-\AbstandY+-\Abstand,\iC=65+1}{\AnzahlY}{\rput(-0.5,\nY){\char\iC}}%
    %
%Wellplates
\multido{\nY=-\AbstandY+-\Abstand,\iX=1+1}{\AnzahlY}{%
    \multido{\nX=\AbstandX+\Abstand,\iY=1+1}{\AnzahlX}{%
        \Cnode[radius=\Radius](\nX,\nY){N\iX\iY}}}%
%Now I want to change color from red to light red for Well A1 to A5
\multido{\iA=1+1}{\AnzahlX}{%
    \pscircle[fillstyle=solid,fillcolor=foo!!+](N1\iA){\Radius}}
\end{pspicture}

\end{document}

具体到您按顺序更改 A1 到 A6 颜色的示例，您可以添加选项，例如用特定颜色填充节点。下面我添加了fillstyle=solid确保第一行已填充并fillcolor=red!<C>!lightred成为填充颜色；测量和<C>之间的颜色份额（定义为和的混合），该份额从 100% 减少到最后一个圆圈中的（几乎）100% 。redlightredredwhiteredlightred

\documentclass{article}

\usepackage{pst-node,multido,fp}

\begin{document}

\FPset{\AnzahlX}{6}
\FPset{\AnzahlY}{4}
\FPset{\AbstandX}{1.57}
\FPset{\AbstandY}{1.47}
\FPset{\Abstand}{1.88}
\FPset{\Durchmesser}{1.5}
\FPdiv\Radius\Durchmesser{2}

\colorlet{lightred}{red!30!white}

\begin{pspicture}(0.7,-0.7)(12.9,-8.7)%
  %Rahmen
  \pspolygon(0,0)(12.8,0)(12.8,-8.2)(12.4,-8.6)(0,-8.6)%
  %Beschriftung
  \multido{\nX=\AbstandX+\Abstand,\iN=1+1}{\AnzahlX}{\rput(\nX,0.5){\iN}}%
  \multido{\nY=-\AbstandY+-\Abstand,\iC=65+1}{\AnzahlY}{\rput(-0.5,\nY){\char\iC}}%
  %Wellplates
  \multido{\nY=-\AbstandY+-\Abstand,\iX=1+1}{\AnzahlY}
    {\multido{\nX=\AbstandX+\Abstand,\iY=1+1,\iC=100+-16}{\AnzahlX}
      {\ifnum\iX=1
         \Cnode[radius=\Radius,fillstyle=solid,fillcolor=red!\iC!lightred](\nX,\nY){\iX\iY}
       \else
         \Cnode[radius=\Radius](\nX,\nY){\iX\iY}
       \fi
      }
    }%
\end{pspicture}

Now I want to change color from red to light red for Well A1 to A6

\end{document}
