Probably because Groff 1.18 produces SGR color escape sequences which
the filter used by Emacs doesn't strip.

A workaround would be to set the environment variable that disables
the SGR escapes in Groff's output.  This could be done in man.el, just
before it runs `man' in the background.  Sorry, I don't remember the
name of the environment variable that does this, but I'm sure it's
documented somewhere in the Groff manual.
