Changing Color in Coordinate Plot in Tikz

I want to change the color in alternates of red and blue. So far I only have:

 documentclass{article}

 usepackage{tikz}



 begin{document}

 begin{center}

 begin{tikzpicture}[scale=.8]

  % Axes

 draw [-latex] (-1,0) -- (12,0) node (xaxis) [right] {$x$};

 draw [-latex] (0,-1) -- (0,6.5) node [above] {$y$};

  % Origin

 node at (0,0) [below left] {$0$};

 % Points

 coordinate (start) at (1,1.5);

 coordinate (1) at (3,.5);

 coordinate (2) at (5.5,4.5);

 coordinate (3) at (7.5,2.75);

 coordinate (end) at (9,6);

 % Plot

 draw [red,thick,-] (start) to[out=-30,in=180] (1) to[out=0,in=180]

  (2) to[out=0,in=110] (3) to[out=45,in=225] (end);



 % show the points



 foreach n in {start,1,2,3,end} fill [black] (n)

   circle (2pt) node [below] {}; 



  end{tikzpicture}

 end{center}

 end{document}

This outputs:

enter image description here

Any advice how to make the color alternative between red and blue with one color between each point?

Some improvements in the code.

standalone class to produce a single draw.

You can scope the lines to set the line width once.

You don't need to insert node in the bullets.

black is the default color, don't need to pass it to fill.

enter image description here

documentclass[tikz,margin=2mm]{standalone}



begin{document}

begin{tikzpicture}

% Axes

draw [-latex] (-1,0) -- (12,0) node (xaxis) [below] {$x$};

draw [-latex] (0,-1) -- (0,6.5) node [left] {$y$};



% Origin

node at (0,0) [below left] {$0$};



% Points

coordinate (start) at (1,1.5);

coordinate (1) at (3,.5);

coordinate (2) at (5.5,4.5);

coordinate (3) at (7.5,2.75);

coordinate (end) at (9,6);



% Plot

begin{scope}[thick]

draw [red]         (start) to[out=-30,in=180] (1);

draw [red!60!blue] (1)     to[out=0,in=180]   (2);

draw [red!30!blue] (2)     to[out=0,in=110]   (3);

draw [blue]        (3)     to[out=45,in=225]  (end);

end{scope}



% show the points

foreach n in {start,1,2,3,end}{%

  fill (n) circle (2pt); 

}

end{tikzpicture}

end{document}

you broke it up in parts and then redefined the color. Thanks, for some reason I kept thinking that it wasn't possible.
