I use the following setting. The keywords are correctly recognized and are
in bold face, but not in color. Are there any other steps for colors.

(require 'ox-latex)
  (add-to-list 'org-latex-packages-alist '("" "listings"))
  (add-to-list 'org-latex-packages-alist '("" "color"))

Also, thank you for reminding me of the `apropos`.
