用色带代码绘制电阻

Question

我想画出这个电阻。每个人都会问我你试过什么？但我是第一个用户，我只能在 latex 中输入和知道一些代码。如果你仔细看看这个电阻，请与我分享。

\documentclass[border=2mm]{standalone}
\usepackage{tikz}
\begin{document}
% \Stripe{offset}{color} long stripe
\newcommand\Stripe[2]{\draw[fill=#2,#2] ++(#1,0) +(-0.15,-0.71) rectangle +(0.15,0.71);}
% \stripe{offset}{color} short stripe
\newcommand\stripe[2]{\draw[fill=#2,#2] ++(#1,0) +(-0.15,-0.51) rectangle +(0.15,0.51);}
\begin{tikzpicture}
  % wire
  \draw[gray,fill=gray!40] (-3,-0.2) rectangle (3,0.2);
  % resistor
