Editing existing figures to overlay with different colors

I have several figure files with the same number of subplots that I need to edit and overlay, subplots1.fig, subplots2.fig, and subplots3.fig.

The problem is that they are all plotted in red and when plotted on top of each other become indistinguishable. Is there a simple way to change the color of a line plotted on a figure before overlaying it on another figure? Loading and rewriting the data to plot later would be very expensive and untimely.

Regards,

Use this.

 if true
f1 = open('f1.fig');
f2 = open('f2.fig');
a1 = get(f1, 'Children');
a2 = get(f2, 'Children');
for i = 1 : numel(a2) 
   a2Children = get(a2(i),'Children');
   copyobj(a2Children, a1(i));
end 
close(f2)
save_figure('f3')
  end

Hi Yuvaraj V, thanks for your reply. This script overlays the plots, but I do not see how it changes the colors. Could you elaborate on changing the colors?

Depending on how you want to change the colors, you can try using shade.m to make it darker or tint.m to make it brighter.
