Gimp.

With an indexed image of course,

To see the map: Colors->Map->Rearrange ColorMap
(right click for sorting...)

To actually play with the palette: "on toolbox, click on the left
pointing arrow/triangle in a box, (top right of bottom panel, under the
ink/paper colour rectangle)"->Add tab->colormap

Enjoy!
