As of the next reboot there will be an easier way to export/import all your
colour settings using "change colour" command.
To "export" the settings, use "change colour show". This will show your current
settings as a single command that can be used to restore those settings at some
later point in time (or, of course, with another character).
> change colour show
change colour all default, say bold WHITE on red
and later you can enter that command again:
> change colour all default, say bold WHITE on red
Set all colours to default.
Changed say colour.
