Filling polygons with color

Question

Is there any good tutorial/approach in LaTeX for drawing polygons filled with color?

EDIT: I would like to use pdfLaTeX interpreter

Answer 1

Sure, you can use TikZ for instance. There is a node shape regular polygon, it can be used like this:

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{shapes.geometric}
\begin{document}
\begin{tikzpicture}
  \foreach \a in {3,...,8}{
    \node[regular polygon, regular polygon sides=\a, minimum size=2cm, anchor=south, fill=blue!40] at (\a*4,0) {};
  }
\end{tikzpicture}
\end{document}

With the following result:

Note that you can determine the color by changing fill=blue!40 to any color definition you like. If you want to add a border to the polygon, you can use the draw option on the node. You can change the color of that by using draw=color. You don't need to use a node, you can of course contruct a regular polygon path, but a node is the easiest way to directly get a regular polygon.
