(font-lock-add-keywords 'latex-mode
 '(("\\(myparencite\\){\\(.*\\)}" (1 font-lock-constant-face)
                                  (2 font-lock-doc-face) )))

Note: If you open a file.tex, you might end up in
TeX-mode or some other mode to do (La)TeX. So, first
see if it works (after evaluation) with

    M-x latex-mode RET

then, if your mode isn't that, make the substitution
in the code.

As you see in the code, use the font-lock-*
faces instead. I'm sure one of yours is green, so
use that.

One way of finding out which one is green is putting
point at a char that has a green face and then invoke
this:

(defun what-face (pos)
  (interactive "d")
  (let((face (or (get-char-property pos 'face)
                 (get-char-property pos 'read-cf-name) )))
    (message " Face: %s" (or face "(no face!)")) ))
