Hi i found this tutorial about segmenting colors from images in

http://www.mathworks.com/help/images/examples/color-based-segmentation-using-k-means-clustering.html

There is a part there wherein the colors has been segmented into 3 part

   for k = 1:nColors
    color = he;
    color(rgb_label ~= k) = 0;
    segmented_images{k} = color;
   end

Now the output is partitioned into 3 separate colors

IE.

image 1 contains only blue

image 2 contains only yellow

image 3 contains only brown

now what i am asking is how can i just get the brown partition? In my example the position of the brown color is 3 but sometimes when i partition other images, The position of the brown color becomes 2. How can i determine what color goes to which partition when using the LAB colorbased segmentation?

Thanks in advance :)
