Sorry for the long title, but that's the summary! I fired up a fresh
Emacs session and used =C-a s search-term RET= to navigate to a
headline in the results by putting the cursor on the line and pressing
RET.

The file text was all black.

If I visited the file directly, I had the typical color-coded text for
headlines/keywords. I decided to replicate with a minimal config, and
I was able to. Here's the context of the min config:

#+begin_min-config
;; set load paths
;; set load dirs and global config options
(add-to-list 'load-path "~/.elisp/org.git/lisp/")
(add-to-list 'load-path "~/.elisp/org.git/contrib/lisp")
#+end_min-config

This was on a work file, and I couldn't initially replicate with a
test file... but it appears it has to do with my header options.
Here's the test file:

#+begin_src org
#+setupfile: "~/org/aux/setupfile.org"
#+options: <:t num:t author:t creator:nil tags:t toc:nil date:t
#+latex_header: \usepackage{lscape}
#+latex_header: \usepackage{amsmath}

* Test headline

Some paragraph just to give me a keyword to search for

** Sub headline

Some more text in the next headline
#+end_src

My process:
- emacs -Q
- M-x load-file RET ~/path/to/min-config RET
- C-x C-f /path/to/file.org RET
- C-c [ to add to agenda list
- C-x C-k RET to kill buffer
- M-x org-agenda RET s RET text RET
- Navigate to test.org matching line RET
- File looks like attached pic

I deleted everything but my #+setupfile line and it still does that.

Without any #+ options at the top of the file, it appears in color.
