化学大分子中轨道的颜色变化

Question

我正在尝试改变这些轨道的颜色。因此，我希望它们不是透明和蓝色，而是红色和蓝色。我尝试更改设置颜色，但结果只是红色和透明或蓝色和透明。我该如何更改它？

\documentclass{general}

\usepackage{chemfig,chemmacros}
\chemsetup{modules=all}

\begin{document}
\setbondoffset{0pt}
  \chemsetup[orbital]{
    overlay ,
    opacity = .75 ,
    p/scale = 1.6 ,
    s/color = blue!50 , %changing to red!50 is no help%
    s/scale = 1.6
  }
  \chemfig{
    -[:-20]\orbital{p}
    (-[:-150])-\orbital{p}
}
\end{document}

Answer 1

看起来包装默认为黑白色，唯一可用的选项是将上半部分黑色更改为另一种色调，就像您对蓝色所做的那样。

然而，我们可以变通一下，欺骗一下包来产生这个

无需重新定义任何包定义（我同意这是一个临时解决方案）

\documentclass[a5paper]{report}
% \documentclass{general} % I do not have a general.sty
\usepackage{chemfig,chemmacros}
\chemsetup{modules=all}

\begin{document}
\setbondoffset{0pt}
 \chemsetup[orbital]{
    overlay ,
    opacity = .75 ,
    p/color = blue!50 , %setting black to another color%
    p/scale = 1.6
}
  \chemfig{
    -[:-20]{\orbital[phase=-]{p}}{\orbital[half,color=red!75]{p}} %Note a half does not work well inverted so invert p
    (-[:-150])-{\orbital[phase=-]{p}}{\orbital[half,color=red!75]{p}} % and over-strike white half with red half @75%
}
\hspace{12mm}
{  \chemfig{
    -[:-20]{\orbital[phase=-]{p}}{\orbital[half,color=red!75]{p}} %Note a half does not work well inverted so invert p
    (-[:-150])-{\orbital{p}}{\orbital[half,angle=270,color=red!75]{p}} % and over-strike white half with red half @75%
}
\hspace{12mm}
{  \chemfig{
    -[:-20]{\orbital{p}}{\orbital[half,angle=270,color=red!75]{p}}  %Note a half does not work well inverted so invert p
    (-[:-150])-{\orbital{p}}{\orbital[half,angle=270,color=red!75]{p}} % and over-strike white half with red half @75%
}
\end{document}
