If you make this a binary image, you can run it through regionprops. There are a variety of metrics in there that should be usefull in identifying equal shapes. Without much more information, I think this will be enough to get you in the right direction.

Once you've identified the shapes, which we've talked about in your other question, you can use a for loop to reassign your labeled region to the desired number, like 1 for squares = blue, 2 for circles = red, and so on. Then just create the colormap and pass that plus the labeled image in to ind2rgb() to get an RGB image with shapes having the desired color.
