Initial Description
When you put an image in a printable document, you don't want it to have black (or coloured) background.  ImageMagick allows to replace colours even when the coloured regions are non-contiguous.  Arbitrary colour values can be specified with `\#123456` (the backslash is for escaping the #).  If you want to replace similar colours as well, use the `-fuzz` option.
