Like this:

  . Go to a character rendered in that face.

  . Type "C=u C-x =".

  . Emacs will tell you all kinds of info about this character,
    including the face, if any, used to display it.  You can click on
    the face name and get a full description of this face in another
    buffer; that face description has a clickable link to customize
    the face.

Is that what you want?
