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.
