In some soft/hardware environments you do not have any control over the set
of colours that can be displayed. Is it possible to get reasonable results
by using an algorithm analog to Floyd-Steinberg for the case black-white, i.e.
selecting the 'nearest' colour in the palette, and then distributing the error
over the surrounding pixels.
To be more specific: what measure of 'nearness' to use, etc.

Any pointers to literature, algorithms would be appreciated.
