使用 \pgfkeys 的新形狀中的新選項的問題

當我編譯以下程式碼時，使用 \pgfkeys: 在新形狀中的新選項時遇到問題：

\documentclass[border=2mm]{standalone}

\usepackage{tikz,makeshape,filecontents}

% Require makeshape package

\makeatletter

%% Constante para la forma valvula:
\def\gap{0mm}

%% Anchor path:

\def\valvulaanchor{ % Obtiene la caja de texto correcta:

  \pgf@xa=\ctbnex
    \pgf@ya=\ctbney

    % Crea el margen para la forma:

    \advance\pgf@ya by \gap
    % Corrige minheight y minwidth, y outerxsep o outerysep:
    \mincorrect{\pgf@xa}{\pgfshapeminwidth}
    \advance\pgf@xa\pgfshapeouterxsep
    \mincorrect{\pgf@ya}{\pgfshapeminheight}
    \advance\pgf@ya\pgfshapeouterysep
  % Dibuja el anchor con \pgfusepath{stroke}:
  \pgfpathmoveto{\pgfpoint{\pgf@xa}{\pgf@ya}}
  \pgfpathlineto{\pgfpoint{\pgf@xa}{-\pgf@ya}}

  \pgfpathlineto{\pgfpoint{-\pgf@xa}{\pgf@ya}}
  \pgfpathclose 
  % lo siguiente solo para comprobar
  %\pgfusepath{stroke}

}

\makeatother

\pgfkeys{%
    /tikz/color izquierda/.style={fill=#1},
    /tikz/color derecha/.style={fill=#1},
}

\begin{document}

\begin{tikzpicture}[scale=2]

\node[
  valvula,
  minimum width=6mm,minimum height=5.5mm,scale=2,
  color derecha=green,color izquierda=cyan
] (v1) at (0,0) {};

\end{tikzpicture}

\end{document}


I get an erroneous result:

但是，當我分別用 和 替換和\pgfkeys{/tikz/.cd,color derecha}時 ， 代碼有效：\pgfkeys{/tikz/.cd,color izquierda}\pgfsetfillcolor{green}\pgfsetfillcolor{cyan}

請問，有人可以幫助我嗎？先致謝！

概念上類似於 Ulrike 的答案，但僅使用 pgf 鍵，即沒有巨集（表面上）。

將鍵的值儲存在命令中，然後使用它們：
