改变电流和电压箭头的颜色（circuitikz）

目前，只有电流和电压的名称是红色/蓝色。我还希望它们的箭头也是红色/蓝色。如何实现？

编辑：

在...的帮助下https://texdoc.org/serve/circuitikz/0#subsection.5.8我设法给电压着色，但没能给电流着色。

您应该使用手册中提供的用于蓝色箭头的相同技术，并根据电流对其进行调整。您已在图表中指定了所有标签第 5.8.1 节。

A真实的 最小下面是一个示例，还展示了如何以相同的样式手动添加电压电流。

在此处输入图片描述

\documentclass{article}
\usepackage[T1]{fontenc}

\usepackage{circuitikz}
\tikzset{every picture/.style={line width=0.75pt}} %set default line width to 0.75pt
% so it's 0.75pt or 0.9pt???
\tikzstyle{every path}=[line width=0.8pt,line cap=round,line join=round]

\NewDocumentCommand{\fixedvlen}{O{0.44cm} m m O{}}{% [semilength]{node}{label}[extra options]
 % get the center of the standard arrow
 \coordinate (#2-Vcenter) at ($(#2-Vfrom)!0.5!(#2-Vto)$);
 % draw an arrow of a fixed size around that center and on the same line
 \draw[-Triangle, #4] ($(#2-Vcenter)!#1!(#2-Vfrom)$) -- ($(#2-Vcenter)!#1!(#2-Vto)$);
 % position the label as in the normal voltages
 \node[anchor=\ctikzgetanchor{#2}{Vlab}, #4] at (#2-Vlab) {#3};
}
\NewDocumentCommand{\redcurrent}{mm}{% node, label
    % position the circuitikz arrow shape in the normal position and direction
    % but color it red
    \node[currarrow, color=red, rotate=\ctikzgetdirection{#1}] at (#1-Ipos){};
    % ditto for the label
    \node[red,anchor=\ctikzgetanchor{#1}{Ilab}] at (#1-Ipos) {#2};
}

\begin{document}
\begin{circuitikz}[american, straight voltages, scale=0.84]
    \draw (0,0)
    to[C, l=$C_1$, i=, -*, name=ic1, v=] (3.5,0);

    % this an independent, manually positioned red current arrow
    \draw(0,1) node[currarrow, color=red]{} node[above,red] {$I_{L_1}$};
    \draw[blue, -Triangle] (4,1.5) -- (4,-0.5) node[midway, right]{$U_r$};

    \fixedvlen{ic1}{$U_{L_1}$}[blue]
    \redcurrent{ic1}{$I_{C_1}$}

\end{circuitikz}
\end{document}

请注意：

  1. 线宽的设置有冲突；
  2. \usepackage[utf8]{inputenc}已经违约好几年了，但是你可能想要 \usepackage[T1]{fontenc}；
  3. 您正在使用“类”参数（可以）和内部参数（很危险，它们将来可能会发生变化）来设置组件的样式；
  4. scale=0.84变化只有坐标，不是节点大小也不是字体；你可能是指scale=0.84, transform shape那里；那将缩放除线宽之外的任何东西（或多或少）。
