I followed through and can now see the colouring.  What would I have to do in order
to colourise 

("=" org-verbatim verbatim)
("~" org-code verbatim)
("+" (:strike-through t))))
For bold, italic and underline, I am using

(defface my-emphasis-bold
  '((default :inherit bold)
    (((class color) (min-colors 88) (background light))
     :foreground "#a60000")
    (((class color) (min-colors 88) (background dark))
     :foreground "#ff8059"))
  "My bold emphasis for Org.")

(defface my-emphasis-italic
  '((default :inherit italic)
    (((class color) (min-colors 88) (background light))
     :foreground "#a60000")
    (((class color) (min-colors 88) (background dark))
     :foreground "#ff8059"))
  "My underline emphasis for Org.")

(defface my-emphasis-underline
  '((default :inherit underline)
    (((class color) (min-colors 88) (background light))
     :foreground "#a60000")
    (((class color) (min-colors 88) (background dark))
     :foreground "#ff8059"))
  "My underline emphasis for Org.")

(setq org-emphasis-alist
      '(("*" my-emphasis-bold)
    ("/" my-emphasis-italic)
    ("_" my-emphasis-underline)
    ("=" org-verbatim verbatim)
    ("~" org-code verbatim)
    ("+" (:strike-through t))))
