\pgfkeys を使用した新しい図形の新しいオプションに関する問題

次のコードをコンパイルすると、\pgfkeys: を使用した新しい図形の新しいオプションで問題が発生します。

I get an erroneous result:

ここに画像の説明を入力してください

\pgfkeys{/tikz/.cd,color derecha}ただし、と を それぞれと \pgfkeys{/tikz/.cd,color izquierda}に置き換えると、コードは機能します。\pgfsetfillcolor{green}\pgfsetfillcolor{cyan}

ここに画像の説明を入力してください

誰か助けてくれませんか？よろしくお願いします！

概念的には Ulrike の回答と似ていますが、pgf キーのみ、つまりマクロはありません (表面上)。
