Correct.  It can be done as follows

(defface texmark-colour

  '( (default :inherit bold)

     ( ((class color) (background light)) :foreground "#00FF00" )

     ( ((class color) (background dark))  :foreground "#00FF00" )

     (t :inherit font-lock-builtin-face) )

  "User defined colour typeface for tex command keywords.")

(defconst texmark-cluster

  `(
    
    (,(rx "\\" word-start (group (or "alpha" "beta" "chi" "delta"

          "Delta" "epsilon" "varepsilon" "eta" "gamma" "Gamma" "iota"))

          word-end)

     (1 'texmark-colour))

and so on
 
Finally doing

(defun texmark-typeface-enable ()

  "Sets the highlight colour for tex commands."

  (font-lock-add-keywords nil texmark-cluster t)

  (font-lock-flush))

There can be certain instances where cdlatex might not work for certain 
environments.  I think that cdlatex
looks at the math context, and if it not as expected, the commands do nothing.  
Se really it is not so general
as it ought to be.
