Defining custom colors

[Michael Hudson]

I've just built emacs from CVS with Carbon support for MacOS X.

Nice!

Now I want to get the colors /just right/.

Specifically, I want to set the background to a color that's not in
the output of list-colors-display.

How can I do this?  I used to use X resources, but obviously that's
not going to work under Aqua.  I thought I used to know how this was
done, but I've forgotten and google isn't helping me.

Any help appreciated!

Cheers,
M.

  the above up, in the hope that it corresponds to reality.
