SYNOPSISppmchange oldcolor newcolor [...] [ppmfile]
Reads a portable pixmap as input. Changes all pixels of oldcolor to
newcolor, leaving all others unchanged. Up to 256 colors may be
replaced by specifying couples of colors on the command line.
The colors can be specified in five ways:
o A name, assuming that a pointer to an X11-style color names file
was compiled in.
o An X11-style hexadecimal specifier: rgb:r/g/b, where r g and b
are each 1- to 4-digit hexadecimal numbers.
o An X11-style decimal specifier: rgbi:r/g/b, where r g and b are
floating point numbers between 0 and 1.
o For backwards compatibility, an old-X11-style hexadecimal num‐
ber: #rgb, #rrggbb, #rrrgggbbb, or #rrrrggggbbbb.
o For backwards compatibility, a triplet of numbers separated by
commas: r,g,b, where r g and b are floating point numbers
between 0 and 1. (This style was added before MIT came up with
the similar rgbi style.)
