Colorize sides regular polygon

To illustrate what edge-coloring is, I'd like to colorize a regular polygon. I want to generate the shape using TikZ, then colorize the sides (edges) of the polygon separately, for instance by doing something like this:
draw[red] (polygon.side 1);
Unfortunately, the world does not seem to work like this. For now my ugly workaround is to overdraw using dotted, dashed, and thick lines.
documentclass{standalone}
usepackage{tikz}
usetikzlibrary{shapes.geometric,positioning}
begin{document}
begin{tikzpicture}
node[draw, dotted, minimum size=2cm, regular polygon,
regular polygon sides=5] (polygon) {};
draw[thick] (polygon.corner 1) -- (polygon.corner 2);
draw[dashed] (polygon.corner 2) -- (polygon.corner 3);
draw[thick] (polygon.corner 4) -- (polygon.corner 5);
draw[dashed] (polygon.corner 5) -- (polygon.corner 1);
end{tikzpicture}
end{document}
Thanks!

With regular polygon colors
option, there's no need for extra commands to draw the sides. Everything is done within the node command.
documentclass[tikz,border=3.14mm]{standalone}
usetikzlibrary{shapes.geometric, positioning}
begin{document}
begin{tikzpicture}[
regular polygon colors/.style 2 args={
append after command={%
pgfextra
foreach i [count=ni, remember=ni as lasti (initially #1)] in {#2}{
draw[i] (tikzlastnode.corner lasti) --(tikzlastnode.corner ni);}
endpgfextra
}
},
]
node[minimum size=2cm, regular polygon,
regular polygon sides=5,
regular polygon colors={5}{red,blue,orange,green,cyan}] (polygon) {};
node[minimum size=2cm, regular polygon,
regular polygon sides=7,
regular polygon colors={7}{red, blue, orange, green, cyan, violet, brown},
right=of polygon] (polygon2) {};
end{tikzpicture}

Here is a proposal that defines a style polygon side
which can be used e.g. like draw[red,polygon side=2];
to draw the second side red.
documentclass[tikz,border=3.14mm]{standalone}
usetikzlibrary{shapes.geometric}
begin{document}
begin{tikzpicture}[get next vertex/.code n args={2}{%
pgfmathparse{int(1+mod(#1,5))}
xdef#2{pgfmathresult}},
polygon side/.style={get next vertex={#1}{tmpnextn},
insert path={(polygon.corner #1)-- (polygon.corner tmpnextn)}}
]
node[draw, dotted, minimum size=2cm, regular polygon,
regular polygon sides=5] (polygon) {};
foreach X [count=Y] in {red,blue,orange,green,cyan}
{draw[X,polygon side=Y];}
end{tikzpicture}
end{document}
Note that as of now the number of corners (or sides) as well as the name of the object (or node), polygon
, are hard coded. One could of course use pgfkeys to store them in some keys, and if you ask me to I'll be happy to add this to this answer.
