Coloring the cluster with same colors as defined for ground truth for visualization

[poster]

Example: (Consider the platform = MATLAB)

Ground_Truth_Indices = [ 1, 1, 1, 2, 2, 2, 3, 3, 3];

For each unique index in the GT, I have defined a color array.

Color_Array = [ 0, 255, 0;  255, 0, 0;  0, 0, 255]; #assuming (in this eg.) the max. cluster size is 3

Next, I use a clustering algorithm (DBSCAN in my case) and it gives the following indices:

Clustered_Indices = [2, 2, 2, 3, 3, 3, 1, 1, 1];

Now, I need to visualize the results alongside the ground truth.
But the obtained indices, after clustering, are different from the ground truth indices.

Thus, according to the color array defined, I would not get the same pattern of colors for ground truth and obtained clusters during visualization. Is there any solution so that I could make both the colorings consistent?

Note: The indices obtained after the clustering cant be predefined and depends on the clustering algorithm and clustering input.
