[Orgmode] How to change colour theme during export

[Dan Davison]

How do I set the color theme for fontification of exported source
blocks? I thought maybe I could do it by adding the desired
(color-theme-whatever) to my org-src-mode-hook. But it doesn't seem to
have any effect (although the hook is called). So how should I do it and
why didn't my method work?

Thanks,

Dan

p.s. The bit in org-exp.el (from l. 2334) that (I believe) does the
htmlize-ing looks like this

--8<---------------cut here---------------start------------->8---
  (with-temp-buffer
    (insert rtn)
    (if (functionp mode)
        (funcall mode)
      (fundamental-mode))
    (font-lock-fontify-buffer) ;; I tried switching this line with the next,
    (org-src-mode)             ;; but that wasn't it.
    (set-buffer-modified-p nil)
    (org-export-htmlize-region-for-paste
     (point-min) (point-max))))
--8<---------------cut here---------------end--------------->8---
