Hi Eric,

Thanks for looking into this.

Here's a simple fix, though I suspect Nicolas will have a more through
solution up his sleeve.

Of course, in org-html--build-head the mysterious :html-htmlized-css-url
is required so you won't actually get any default colors, which is a bit
boring in my opinion.  I don't know if I'm misunderstanding
:html-htmlized-css-url, a bug or something supposed to be set via a
publish project.
