Hi Seb,
Thanks for sharing this code. I couldn't help myself but to turn it
into a patch as that has become my favorite way of reviewing new code.
The resulting patch it attached.

I noticed a couple of issues in the applied patch (possibly due to a
transcription error on my part). Namely
- I believe your default faces only work for white backgrounds
- I didn't notice a change in background for the code blocks
- it seems that the #+end_src line is fontified but the #+begin_src line
is not
An image of my Emacs after applying the patch is available at:

Thanks for sharing, I hope this feedback is helpful.
