Ah, this would be problematic. In server side applications the same filter function is used by multiple threads in parallel, so making it stateful is tricky (one can use thread locals, but then they also have to be cleaned up, failure to do that results in the web application leaking permanent generation memory on undeploy). If one really needs a guarantee that no two adjacent polygon get the same color it's better to do that deterministically, and in pre-processing.
