	I believe that the term "coloring" is used by professional
typesetters to describe intercharacter spacing, i.e. the look of a document
when the character kerning is uniformly wider or narrower than usual.  I am
trying to typeset some text with special intercharacter separation.  TeX
appears to assume a natural width defined when the font is created without
any adjustment parameter for characters equivalent to \baselineskip's effect
on lines.  "\hbox spread XXpt{}" only affects interword spacing not
intercharacter spacing, and I cannot create a separate font or TFM file for
each coloring change.  The closest parameter is the \sfcode table, but I
cannot find any mechanism whereby all of the entries may be quickly changed
by a uniform factor.  Currently I am kerning each and every character to
obtain the correct spacing.  Is there any better solution?
