Change to default line colors

I have a saved .fig file in one of my directories, I have managed to import the fig file as an object in the workspace with f = openfig(path). The figure currently uses a custom line coloring scheme, is there any way I can revert back to the default line coloring by manipulating the properties of the object?

I tried changing the Children of the Axes property but it seems to only change the color of a single line at once, I am trying to do it for all children of this property at once.

This worked for me. it will produce a random blank figure which is used to find the default 'colorOrder'. It then replaced the colorOrder of the figure I had saved and opened.

fig_name='random_figure.fig';
figure; 
x=1:10;
y1=x; y2=2*x;y3=3*x;
plot(x,y1,'r',x,y2,'b',x,y3,'k');
legend('y1','y2','y3');
saveas(gcf,fig_name);
figure;
def_clr_order=get(gca,'colorOrder'); % called before plotting anything, just to find the default color order
f = openfig(fig_name);
plts = allchild(gca);
for i=1:length(plts)
set(plts(i),'Color',def_clr_order(i,1:3));
end

Output:
