There are a lot of papers about palette-based compression. Most of the research 
beats JBIG by a margin in it's own territory, b/w in the end is just a two-color 
palette.
In your three color case, if you have no better inspiration, just code two 
planes (a: is it color 0 or the others?, b: is it colour 1 or the others?, c: is 
implicit).
