How can I replace the color #234567 in all pixels by the color #223344 ?

As the subject already said I am searching for a way to replace all pixels with the color #234567
in a currently existing picture with the color #223344.

How can I do this with IM?

Use the -opaque option for the convert command.

...and how would the full command line look like?

convert <infile> -fill "#223347" -opaque "#234567" <outfile>
