Emacs font-lock highlighting weirdness

Question

I have code to change default color theme. I prefer this way because I add more classes then default font-lock .

(defmacro /construct-face (name comment &rest args)
    "Define face and specify attributes."
    (list 'progn
          (list 'defface name nil comment)
          (nconc (list 'set-face-attribute (list 'quote name) nil) args)))

(/construct-face ⋅function-name "Face to highlight functions."
                  :foreground "SlateBlue")
(setq font-lock-function-name-face '⋅function-name)
(/construct-face ⋅comment "Face to display comments"
                  :foreground "gray20"
                  :bold t)
(setq font-lock-comment-face '⋅comment)

Weirdness is that comment colors became gray, but function's names did not became purple. What is the difference and what should I try to check?

因为它不是“ gray20”而是"grey20" ，所以我昨天也犯了这个错误，但是使用了grey10。
