How do I make matlab legends match the colour of the graphs?

Here is the code I used:

x = linspace(0,2);
e = exp(1);
lin = e;
quad = e-e.*x.*x/2;
cub  = e-e.*x.*x/2;
quart = e-e.*x.*x/2+e.*x.*x.*x.*x/24;
act = e.^cos(x);
mplot = plot(x,act,x,lin,x,quad,x,cub,x,quart);
legend('actual','linear','quadratic','cubic','quartic')

This produces a legend matching the right colors to actual and linear, then after that it seems to skip over red on the graph, but not on the legend, i.e. the legend says quadratic should be red, but the graph shows it as green, the legend says cubic should be green, but the graph shows it as purple etc.

Any help is appreciated.
