Depends on how much intelligence you put into your image format.  I
wrote a program to convert from xpm to xbm which would do the color
conversions the way I wanted them.  You draw the xpm and then you
specify conversions like this:
--
white   gray50
None    white
dodger blue     white
blue    black
firebrick       black
goldenrod       black
yellow  gray75
sienna  black
pale green      black
chocolate       white
--
The conversions then get taken through the ppmtopgm | pgmtopbm |
pbmtoxbm pipeline which produces quite usable pictures.
The program is available from madhatter.ws.cc.cmu.edu:pub/xpmtoxbm.pl,
and the stuff I drew as KhoiKhoi.tar.gz
