The string

<style> .string {color: #ff4500;}</style>

is in the html file, but it is not used - the color is hardcoded as
#ffff00:

<span style="color: #ffff00;">"seed"</span>

Here is an example .org file:

- ---------------------------
#+STYLE: <style> .string {color: #ff4500;}</style>
* Results
#+begin_src R :exports code
    plot(
         res,
         stages=c(
           "flower",
           "parFlower",
           "gall",
           "midgeAdult",
           "grePod",
           "weavilAdult",
           "seed"
           ),
         plot.type="multiple"
         )
#+end_src
- ---------------------------

and the resulting html file:

The question is: how can I change the  "color: #ffff00;" for the
strings, e.g. in

<span style="color: #ffff00;">"seed"</span>

to any other color?

Cheers,

Rainer
