How about converting the TIF files to XPM format? These files have a
header like in this multi-colour example:
" c #01c601c601c6",
". c Gray40",
"X c #a527a527a527",
"o c #da22da22da22",
"O c None",
To make the XPM file with this header monochrome, you'll just need to
change every colour that is not "None," or "white," or
"Grey100" (possible synonyms for "no colour here," transparency is
unknown) to "Black." Then you could change the characters
representing the original non-white colours (i.e. SPC, ., X, and o in
my example) to one of these characters, best the SPACE character.
Then you could delete the duplicate colour mappings. Finally convert
XPM -> TIFF.
XPM is completely US-ASCII. Each particular character stands for one
particular colour as mapped in the file's header. If more than about
60 colours are used, then all the colours are encoded by pairs of
Almost anything is easier to get into than out of.
