I don't know why it doesn't work for you on macOS (sounds like a bug
specific to that platform, or maybe also to the specific Emacs version
you are using, which is quite old), but the recommended way of
customizing the colors is via default-frame-parameters, which you can
set in your init file.  There are examples of that in the Emacs user
manual, and all of the colors you want to change have corresponding
frame parameters.

Of course, it could be that the same bug which prevents the
command-line arguments from working will also defeat the
default-frame-parameters customization...
