Superimpose multiple images with same colormap

Working on a project of tracking cell trajectory (time lapse) on a petri dish.

I have 2 images that i used the watershed feature to dispose of the background and have been left with Image 1 and Image 2:

Let's say i have 20 pictures like this, how might I superimpose (or do I want to overlay?) one on top of another that can create a colormap to represent time?

This might help:

final_image=imoverlay(image1,image2,[1 0 0]);
%1 0 0 corresponds to red overlaying if you want any other
%color change accordingly, also make sure both the images have
%equal dimensions.

Or you can also use this code:

if true
   ix(1)=image1;
   ix(2)=image2;
  for i=3:20
       ix(i)=imfuse(ix(i-2),ix(i-1)); %specify certain method if you want
  end

end
