Ubuntu的logo绘制TikZ代码分享

这里那么其ubuntu的logo如何绘制呢？代码如下：

\documentclass[margin=10pt]{standalone}
\usepackage{graphicx}
\usepackage{tikz}
  \pgfdeclarelayer{fg}
  \pgfsetlayers{main,fg}
  \newcommand\rad{3cm}
  \definecolor{myred}{RGB}{212,0,0}
  \definecolor{myorange}{RGB}{244,72,0}
  \definecolor{myyellow}{RGB}{251,139,0}

  \newcommand{\hug}[3]{
    \begin{scope}[shift={(0,0)}, rotate=#1]%
      \draw[#2, line width=1.5cm] (\rad,0) arc (0:120:\rad)%
      node[circle, fill=#3, minimum size=1.9cm,%
      draw=white, line width=2.8mm] at (57.5:\rad*1.3) {};%
      \begin{pgfonlayer}{fg}%
        \node[rectangle, fill=white, rotate=#1,%
        minimum height=3mm, minimum width=1.6cm] at (\rad,0) {};%
      \end{pgfonlayer}%
    \end{scope}%
  }

\begin{document}
\begin{tikzpicture}
  \foreach \angle/\cola/\colb in {
    0/myorange/myred,
    120/myyellow/myorange,
    240/myred/myyellow}{
    \hug{\angle}{\cola}{\colb}
  }
\end{tikzpicture}

\end{document}
