Coloring labelled regions (or states) [message #92064]

Hi,
I have an image where I identified regions (label_region). These regions are confining with one another as states do on a political map.
Can you suggest me a way to generate a colored image, so that I don't have neighboring "states" with too similar colors?

I can fill in the array values, I just dunno where to get appropriate colors or how to chose which one gets which.

I would be happy to get any information on how to do this. Something tells me that Brewer colors are the way to go, but I haven't figured out which one to use for which state...

Thanks,
Helder

PS: My problem has nothing to do with political maps, but that's a good approx. I'm not sure how many neighbors each region will have, but it should be comparable to typical values for political maps.
