Thanks for your response.  I saw your patch in git and may I suggest to
extend it to:

--8<---------------cut here---------------start------------->8---
  ;; Ditto for environments with optional args
  (mapc (lambda (entry)
          (add-to-list 'LaTeX-auto-environment
                       (list (nth 0 entry) 'LaTeX-env-args (vector "argument")
                             (1- (string-to-number (nth 1 entry))))))
        LaTeX-auto-env-args-with-opt)
--8<---------------cut here---------------end--------------->8---

The definition above then results in

    ("colorenv" LaTeX-env-args ["argument"] 1)

in (LaTeX-environment-list) and AUCTeX asks for the optional argument
while inserting the environment.

Best, Arash
