Actually, now I can again reproduce it.  The problem seems to be tikz:
With tikz in the latex header, foreground is always black.  So probably
more a LaTeX-issue?

Example: Change the :foreground color in org-format-latex-options to
"Red" and do the preview (C-c C-x C-l) on this subtree:

#+begin_org
#+LATEX_HEADER: \usepackage{tikz}


* Test 
  Hi, 

  set :foreground in org-format-latex-options to "Red" and take this
  fragment $1 = 2$ and press C-c C-x C-l.
#+end_org


So the question becomes:
Can I make the foreground changing work even with tikz loaded in the
latex document?

Cheers,
Andreas
