Those are good heuristics for those specific cases I guess.
My experience is that this local optimum algorithm is perfectly fine for finding colors. I can't really say that the results of p4fliconv is really better than the results of my (work in progress) optimizer and p4fliconv also uses brute force for finding colors. So, brute force search for colors looks like an overkill to me.
What really can change the quality of the results is finding good values for the "global" parameters of the picture like xshift. My hope is that some heuristic search for non-color values combined with local optimum search for colors (which will tell which "global" value can yield better results overall) will produce good results. I am yet to find out ...
