i found this post fixing one of my two problems: circuittikz colored current arrows It redefines the color of the current arrows. What I also want to have is the label of the current being written in the same color. Is there a (easy) way to manage this?

Thank you in advance.

  • There is always i={\color{\pgfkeysvalueof{/tikz/circuitikz/current arrow color}}...} Oct 9, 2017 at 22:37
  • But how exactly? Oct 18, 2017 at 12:35

It turns out the old solution no longer works, so I revised it. Also, one can simply use \color{red} (for example) in any text field, or [color=red] in a draw command to change the text color.


\ctikzset{current arrow color/.initial=black}% create key

            \pgf@circ@res@step = \pgf@circ@Rlen
                \divide \pgf@circ@res@step by 16
        \pgf@x  =\pgf@circ@res@step

            \pgf@circ@res@step = \pgf@circ@Rlen
            \divide \pgf@circ@res@step by 16

            \pgfsetcolor{\pgfkeysvalueof{/tikz/circuitikz/current arrow color}}



\ctikzset{voltage/distance from node=.8}

\draw[circuitikz/current arrow color=red]
% bottom line           
    (0,0)  to [short,o-o] (11,0)
% shunt branches            
    (2,0) to [C, *-*,l={$C/2$},v=$V_C$] (2,3)
    (9,0) to [C, *-*,l=$C/2$,n=C2] (9,3)     
% top line          
    (0,3) to [short,o-] (3,3)
    to [R, l_=$R$,i={\color{\pgfkeysvalueof{/tikz/circuitikz/current arrow color}}$I_1$}] (5,3)
    (5,3)  -- (6,3)
    to [L, l_=$L$] (8,3)
    to [short,-o] (11,3)
% Input and output labels
    (C2.s)  node[right] {$V_s$};% anchors rotated
\draw[<->,color=red] (11,0.2) -- (11,2.8) node[midway,fill=white] {$V_r$};
