emacs color White on Black setup question

[Xah Lee]

emacs color setup question.

normally i start emacs without changing any color theme stuff. Default
is just fine for me.

but sometimes, i want the background black. The problem is, you can't
simply set background to black, you'll also need to change a bunch of
default text colors.

is there a simple way to set background to black and other colors
automatically set to readable?

Note: i rather not install any of those color theme stuff.
This is emacs running GUI on Windows, not in terminal. So, no X11 or
terminal/ANSI color setup involved. Just pure emacs.

thanks.
