I have a dark background for my console so there's quite a bit of journalctl output that is unreadable.
I see lots of information about how to add color! But how do I completely disable it?

you can disable colour in journalctl like so;
you could then add it to your ~/.bashrc, exporting the env variable;
That will be global though and may effect other systemd related things.
I guess a more direct solution would be to add an alias to your ~/.bashrc, like so;
alias journalctl='SYSTEMD_COLORS=false journalctl'
