I'm trying to start emacs on a random machine, some random, unknown 
configuration, and I can't read it because of the color settings.

What's the command line option to tell it to stop using color?

Many people can't discriminate colors unless they're set up by a color 
professional who understands color vision.  Most aren't. And I can't see it.

On my private configurations, I can set them to turn off font-lock mode, 
but from the command line, even --eval='(global-font-lock-mode 0)' 
doesn't seem to be working.

Incredibly frustrating.

Do you mean in the terminal?  Try '--color=never'.

Didn't help.  Still colored.

Perhaps the configuration explicitly enables font-lock?  Why not use -Q
so you don't have to deal with random configurations?

    emacs -Q --eval='(global-font-lock-mode 0)'

I don't there is any command line option to disable colour in graphical
mode.  Possibly you could disable font-lock later, e.g.,

    emacs --eval='(add-hook (quote after-init-hook) (lambda () (global-font-lock-mode 0)))'

To completely get rid of all colour, you could evaluate:

    (dolist (face (face-list))
      (when (face-foreground face)
        (set-face-foreground face 'unspecified))
      (when (face-background face)
        (set-face-background face 'unspecified)))

(again, this would probably have to be done in the after-init-hook, if
the configuration makes its own colour settings to faces)

Thank you.

Looks like I needed: emacs -Q -nw --color=never.

I can chase it down from there.
