This is working well, except in this situation -

--8<---------------cut here---------------start------------->8---
 \myparencite{1767}[18] and N-methyl-serotonin \parencite{ }[19]. 
--8<---------------cut here---------------end--------------->8---

where the green colouration continues after \myparencite into the
following text, and even colouring the \parencite which has not yet been
worked on.

These two lines are from my theme, if its relevant, -

--8<---------------cut here---------------start------------->8---
 '(font-lock-constant-face ((t (:foreground "#A6E22E"))))
 '(font-lock-doc-face ((t (:foreground "#EEDC82"))))
--8<---------------cut here---------------end--------------->8---

But it is usable so thanks very much. 

Thanks
Sharon.
