I have the following for when I use org-tree-slide-mode for
presentations, where my colour theme is light text on dark background:

#+begin_src emacs-lisp :results none
  (setq org-format-latex-options '(:foreground "white" :background "black" :scale 3 :html-foreground "Black" :html-background "Transparent" :html-scale 1.0 :matchers ("begin" "$1" "$" "$$" "\\(" "\\["))
        org-latex-create-formula-image-program 'imagemagick
        org-tree-slide-heading-emphasis t
        )
#+end_src

I think the key is the =org-format-latex-options= variable.  I have no
idea whether this is used by the exporter or just for previewing LaTeX
in org.
