Is it possible to make all resistors red (or all capacitors blue, etc) in circuitikz?

Question

Is it possible to make circuitikz draw all resistors red or all capacitors blue? I can make all bipoles thick, for example, but cant make all resistors red. I have to write the color explicitly. I cannot find a ctikzset command for this. This is an example. I want to get rid of the color=red for all resistors.

\documentclass{standalone}
\usepackage[american,cuteinductors]{circuitikz}
\usetikzlibrary{shapes,arrows,circuits,calc,babel}
\usepackage{pgfplots}
\pgfplotsset{compat=1.12}

\begin{document}
\begin{tikzpicture}[transform shape, scale=1.0,thick]
\ctikzset{bipoles/thickness=2}
\ctikzset{label/align = smart}
\draw (0, 0) to [battery1, color=green, l=$\mathcal{E}$, invert] (0, 4) -- (4,4) to [R, l^=$R_1$, color=red] (2,2) to [R=$R_2$, color=red] (4, 0) -- (0, 0);
\draw (4, 4) to [R=$R_4$, color=red] (6, 2) to [R = $R_3$, color=red] (4, 0);
\draw (2, 2) to [C = $C$, color=blue] (6,2);
\end{tikzpicture}  
\end{document}

Thanks in advance. Edit: Making the code compilable.

You can use \tikzset{R/.append style={color=red}} (see pgfkeys documentation page 888):

\documentclass{standalone}
\usepackage[american,cuteinductors]{circuitikz}
\usetikzlibrary{shapes,arrows,circuits,calc,babel}
\usepackage{pgfplots}

\tikzset{
    R/.append style={color=red},
    C/.append style={color=blue},
    battery1/.append style={color=green},
}

\begin{document}
\begin{tikzpicture}[transform shape, scale=1.0,thick]
\ctikzset{bipoles/thickness=2}
\ctikzset{label/align = smart}
\draw (0, 0) to [battery1, l=$\mathcal{E}$] (0, 4) -- (4,4) to [R, l^=$R_1$] (2,2) to [R=$R_2$] (4, 0) -- (0, 0);
\draw (4, 4) to [R=$R_4$] (6, 2) to [R = $R_3$] (4, 0);
\draw (2, 2) to [C = $C$] (6,2);
\end{tikzpicture}  
\end{document}

Edit: If you want to change the color of the labels, too, you can use the /tikz/text key:

\tikzset{
    R/.append style={color=red, /tikz/text=red},
    C/.append style={color=blue, /tikz/text=blue},
    battery1/.append style={color=green, /tikz/text=green},
}
